BD4xxM2-C Series
●General Description
The BD4xxM2-C series are low quiescent regulators
featuring 45 V absolute maximum voltage, and output
voltage accuracy of ±2 % ( 3.3 V or 5.0 V: Typ.), 200 mA
output current and 40 μA (Typ.) current consumption.
These regulators are therefore ideal for applications
requiring a direct connection to the battery and a low
current consumption.
A logical “HIGH” at the CTL pin enables the device and
“LOW” at the CTL pin not enables the device.
(Only W: Includes switch)
Ceramic capacitors can be used for compensation of the
output capacitor phase. Furthermore, these ICs also
feature overcurrent protection to protect the device from
damage caused by short-circuiting and an integrated
thermal shutdown to protect the device from overheating
at overload conditions.

●Selection of Components Externally Connected
・VCC Pin
Insert Capacitors with a capacitance of 0.1 μF or higher between the VCC and GND pin. Choose the capacitance
according to the line between the power smoothing circuit and the VCC pin. Selection of the capacitance also
depends on the application. Verify the application and allow sufficient margins in the design. We recommend using a
capacitor with excellent voltage and temperature characteristics.
・Output Pin Capacitor
In order to prevent oscillation, a capacitor needs to be placed between the output pin and GND pin. We recommend
using a capacitor with a capacitance of 10 μF (Typ.) or higher. Electrolytic, tantalum and ceramic capacitors can be
used. When selecting the capacitor ensure that the capacitance of 6 μF or higher is maintained at the intended
applied voltage and temperature range. Due to changes in temperature the capacitor’s capacitance can fluctuate
possibly resulting in oscillation. For selection of the capacitor refer to the data of Figure 41.
The stable operation range given in the data of Figure 41 is based on the standalone IC and resistive load. For actual
applications the stable operating range is influenced by the PCB impedance, input supply impedance and load
impedance. Therefore verification of the final operating environment is needed.
When selecting a ceramic type capacitor, we recommend using X5R, X7R or better with excellent temperature and
DC-biasing characteristics and high voltage tolerance.
Also, in case of rapidly changing input voltage and load current, select the capacitance in accordance with verifying
that the actual application meets with the required specification.

BD4xxM2-C Series
Refer to the heat mitigation characteristics illustrated in Figure 44, 45 when using the IC in an environment of Ta ≥ 25 °C.
The characteristics of the IC are greatly influenced by the operating temperature, and it is necessary to operate
under the maximum junction temperature Tjmax.
Even if the ambient temperature Ta is at 25 °C it is possible that the junction temperature Tj reaches high temperatures.
Therefore, the IC should be operated within the power dissipation range.
The following method is used to calculate the power consumption Pc (W)
Pc = ( VCC - VOUT ) x IOUT + VCC x Icc
Power dissipation Pd ≥ Pc
The load current IOUT is obtained by operating the IC within the power dissipation range.
(Refer to Figure 13, 31 for the Icc.)
Thus, the maximum load current IOUTmax for the applied voltage VCC can be calculated during the thermal design process.
The following method is also used to calculate the junction temperature Tj.
●HTSOP-J8
■Calculation Example 1) with Ta = 105 °C VCC = 13.5 V, VOUT = 5.0 V
At Ta = 105 °C with Figure 44 ② condition, the calculation shows that 125 mA of output current is possible at 8.5 V potential
difference across input and output.
The thermal calculation shown above should be taken into consideration during the thermal design in order to keep the
whole operating temperature range within the power dissipation range.
In the event of shorting (i.e. VOUT and GND pins are shorted) the power consumption Pc of the IC can be calculated as
follows:
Pc = VCC x ( Icc + Ishort ) ( Refer to Figure 10, 28 for the Ishort ) Ishort : Short Current
■Calculation Example 2) with Tc(bottom) = 80 °C, VCC = 13.5 V, VOUT = 5.0 V, IOUT = 80 mA
At Tc(bottom) = 80 °C with Figure 44 ② condition, the power consumption Pc of the IC can be calculated as follows:
Pc = ( VCC - VOUT ) x IOUT + VCC x Icc
Pc = ( 13.5 V - 5.0 V ) x 80 mA + 13.5 V x Icc
Pc = 0.681 W ( Icc = 45 µA )
At the power consumption Pc is 0.681 W, the junction temperature Tj can be calculated as follows:
Tj = Pc x θjc + Tc
Tj = 0.681 W x θjc + 80 °C
Tj = 86.8 °C ( θjc (bottom) = 10 °C/W )
The junction temperature is 86.8 °C, at above condition.
The thermal calculation shown above should be taken into consideration during the thermal design in order to keep the
whole operating temperature range within Tj ≤ 150 °C.

■Calculation Example 1) with Ta = 105 °C VCC = 13.5 V, VOUT = 5.0 V
At Ta = 105°C with Figure 45 ② condition, the calculation shows that 63 mA of output current is possible at 8.5 V potential
difference across input and output.
The thermal calculation shown above should be taken into consideration during the thermal design in order to keep the
whole operating temperature range within the power dissipation range.
In the event of shorting (i.e. VOUT and GND pins are shorted) the power consumption Pc of the IC can be calculated as
follows:
Pc = VCC x ( Icc + Ishort ) ( Refer to Figure 10, 28 for the Ishort )
■Calculation Example 2) with Tc(bottom) = 92 °C, VCC = 13.5 V, VOUT = 5.0 V, IOUT = 80 mA
At Tc(bottom) = 92 °C with Figure 45 ② condition, the power consumption Pc of the IC can be calculated as follows:
Pc = ( VCC - VOUT ) x IOUT + VCC x Icc
Pc = ( 13.5 V - 5.0 V ) x 80 mA + 13.5 V x Icc
Pc = 0.681 W ( Icc = 45 µA )
At the power consumption Pc is 0.681 W, the junction temperature Tj can be calculated as follows:
Tj = Pc x θjc + Tc
Tj = 0.681 W x θjc + 92 °C
Tj = 103.6 °C ( θjc (bottom) = 17 °C/W )
The junction temperature is 103.6 °C, at above condition.
The thermal calculation shown above should be taken into consideration during the thermal design in order to keep the
whole operating temperature range within Tj ≤ 150 °C.
IC stand alone θja = 83.3 °C/W → -12 mW/°C
25 °C = 1.50 W →105 °C = 0.54 W
IOUT ≤0.54 W - 13.5 V x Icc

IOUT ≤ 63 mA ( Icc: 45 µA )

●Operational Notes
1) Absolute Maximum Ratings
Exceeding the absolute maximum rating for supply voltage, operating temperature or other parameters can result in
damages to or destruction of the chip. In this event it also becomes impossible to determine the cause of the
damage (e.g. short circuit, open circuit, etc.). Therefore, if any special mode is being considered with values
expected to exceed the absolute maximum ratings, implementing physical safety measures, such as adding fuses,
should be considered.
2) The electrical characteristics given in this specification may be influenced by conditions such as temperature, supply
voltage and external components. Transient characteristics should be sufficiently verified.
3) GND Electric Potential
Keep the GND pin potential at the lowest (minimum) level under any operating condition. Furthermore, ensure that,
including the transient, none of the pin’s voltages are less than the GND pin voltage.
4) GND Wiring Pattern
When both a small-signal GND and a high current GND are present, single-point grounding (at the set standard
point) is recommended. This in order to separate the small-signal and high current patterns and to ensure that
voltage changes stemming from the wiring resistance and high current do not cause any voltage change in the
small-signal GND. Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external
component GND.
5) Inter-Pin Shorting and Mounting Errors
Ensure that when mounting the IC on the PCB the direction and position are correct. Incorrect mounting may result
in damaging the IC. Also, shorts caused by dust entering between the output, input and GND pin may result in
damaging the IC.
6) Inspection Using the Set Board
The IC needs to be discharged after each inspection process as, while using the set board for inspection, connecting
a capacitor to a low-impedance pin may cause stress to the IC. As a protection from static electricity, ensure that the
assembly setup is grounded and take sufficient caution with transportation and storage. Also, make sure to turn off
the power supply when connecting and disconnecting the inspection equipment.
7) Power Dissipation (Pd)
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in
deterioration of the properties of the chip. The absolute maximum rating of the Pd stated in this specification is when
the IC is mounted on a 114.3mm x 76.2mm x 1.6mmt glass epoxy board. In case of exceeding this absolute
maximum rating, increase the board size and copper area to prevent exceeding the Pd rating.
8) Thermal Design
The power dissipation under actual operating conditions should be taken into consideration and a sufficient margin
should be allowed for in the thermal design. On the reverse side of the package this product has an exposed heat
pad for improving the heat dissipation. Use both the front and reverse side of the PCB to increase the heat
dissipation pattern as far as possible. The amount of heat generated depends on the voltage difference across the
input and output, load current, and bias current. Therefore, when actually using the chip, ensure that the generated
heat does not exceed the Pd rating.
Tjmax: maximum junction temperature = 150°C, Ta: Ambient Temperature (°C), θja: Junction-to-Ambient Thermal
Resistance (°C/W), Pd: Power Dissipation Rating (W), Pc: Power Consumption (W), VCC: Supply Voltage,
VOUT: Output Voltage, IOUT: Output Current, Icc: Circuit Current
Power Dissipation Rating Pd (W) = ( Tjmax - Ta ) / θja
Power Consumption Pc (W) = ( VCC - VOUT ) x IOUT + VCC x Icc
9) Overcurrent Protection Circuit
This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This
protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should
not be used in applications characterized by continuous operation or transitioning of the protection circuit.
10) Thermal Shut Down (TSD)
This IC incorporates and integrated thermal shutdown circuit to prevent heat damage to the IC. Normal operation
should be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction
temperature (Tj) will rise and the TSD circuit will be activated and turn all output pins OFF. After the Tj falls below the
TSD threshold the circuits are automatically restored to normal operation.
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from
heat damage.

11) In some applications, the VCC and pin potential might be reversed, possibly resulting in circuit internal damage or
damage to the elements. For example, while the external capacitor is charged, the VCC shorts to the GND. Use a
capacitor with a capacitance with less than 1000 μF. We also recommend using reverse polarity diodes in series or a
bypass between all pins and the VCC pin.
Figure 50.
12) This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P/N junctions are formed at the intersection of these P layers with the N layers of other elements to create a
variety of parasitic elements.
For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then:
○The P/N junction functions as a parasitic diode when GND > pin A for the resistor, or GND > pin B for the transistor.
○Also, when GND > pin B for the transistor (NPN), the parasitic diode described above combines with the N layer of
the other adjacent elements to operate as a parasitic NPN transistor.
Parasitic diodes inevitably occur in the structure of the IC. Their operation can result in mutual interference between
circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip. Therefore do not
employ any method in which parasitic diodes can operate such as applying a voltage to an input pin that is lower
than the (P substrate) GND.
