BDxxIA5WEFJ
General Description
BDxxIA5WEFJ se ri es devices are LDO regulators with an output current of 0.5A. The output accuracy is ±1% of the output
voltage. Both fixed and variable output voltage devices are available. The output voltage of the variable output voltage
device can be varied from 0.8 to 4.5V using external resistors. Various fixed output voltage devices that do not use external
resistors are also available. It can be used for a wide range of digital appliance applications. It has a small package type:
HTSOP-J8 (4.90mm x 6.00mm x 1.00mm). These devices have built in over current protection to protect the device when
output is shorted, A shutdown mode and thermal shutdown circuit to protect the device during over load conditions.
These LDO regulators are usable with ceramic capacitors that enable a smaller layout and longer life.

Power dissipation
HTSOP-J8
Thermal design should ensure operation within the following conditions. Note that the temperatures listed are the allowed
temperature limits and thermal design should allow sufficient margin beyond these limits.
1. Ambient temperature Ta can be no higher than 85.
2. Chip junction temperature (Tj) can be no higher than 150.
Chip junction temperature can be determined as follows:
Calculation based on ambient temperature (Ta)
Tj=Ta+θj-a×W

Substrate siz e: 70mm×70mm×1.6mm (substrate with thermal via)
Most of the heat loss that occurs in the BDxxIA5WEFJ series is generated from the output Pch FET. Power loss is
determined by the total VCC-VO voltage and output current. Be sure to confirm the system input and output voltage as well as
the output current conditions in relation to the heat dissipation characteristics of the VCC and VO in the design. Bearing in
mind that heat dissipation may vary substantially depending on the substrate employed (due to the power package
incorpora ted in the BDxxIA5WEFJ series) make certai n to factor conditions such as substrate size into the thermal design.
Power consumption [W] = Input voltage (VCC) – Output voltage (VO) ×IO (Ave)
Example) Where VCC=3.3V, VO=2.5V, IO(Ave) = 0.1A,

Input-to-Output Capacitor
It is recommended that a c apac i to r (over 1uF) is placed near pins between the input pin and GND as well as the output pin
and GND. A capacitor, between input pin and GND, is valid when the power supply impedance is high or trace is long. Also,
as for the capacitor between the output pin and GND, the greater the capacitance, the more sustainable the line regulation
will be and the capacitor will make improvements of characteristics depending on the load. However, please check the
actual functionality of this part by mounting it on a board for the actual application. Ceramic capacitors usually have different,
thermal and equivalent series resistance characteristics, and moreover capacitance decreases gradually in use.
For additional details, please check wi th the manufacturer, and select the best cer amic capacitor for your applic ati on.
Equivalent Series Resistance ESR (Output Capacitor)
To prevent oscillations, please attach a capacitor between
VO and GND. Capacitors usually have ESR (Equivalent
Series Resistance). Operation will be stable in the ESR-IO
range shown to the right. Ceramic, tantalum and
electrolytic Capacitors have different ESR values, so
please ensure that you are using a capacitor that operates
in the stable operating region shown on the right. Finally,
please evaluate in the actual application.

Board Lay ou t
PCB layout considerations:
Input capacitor CIN connected to VCC (Vin) should be pla ce d as cl ose to VCC(VIN) pin as possible.
Output capacitor COUT also should be placed as clos e to IC pin as poss ible. In case the part is connected to inner layer
GND plane, please use several through holes.
FB pin has comparatively high impedance and can be affected by noise, so stray capacitance should be as small as
possible. Please take care of this during layout.
Please make GND pattern wide enough to handle thermal dissipation.
For output voltage setting
Output voltage can be set by FB pin voltage (0.800V typ.) and external resistance R1, R2.
(The use of resistors with R1+R2=1k to 90k is recommended)

Operational Notes
(1) Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., c an
break down the device, thus making it impossible to identify the damage mode, such as a short circuit or an open circuit.
If there is any possibility of exposure over the rated values, please consider adding circuit protection devices such as
fuses.
(2) Connecting the power supply connector backward
Connecting of the power supply in reverse polarity can damage the IC. Take precautions when connecting the power
supply lines. An external direction diode can be added.
(3) Power supply lines
Design the PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and supply
line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power supply
terminals to ICs, connect a capacitor between the power supply and GND terminal. When using el ect rol yti c c apaci tors in
a circu it, note that capacitance values are reduced at low temperatures and ov er time.
(4) GND voltage
The potential of the GND pin must be minimum potential under all operating condit ion s.
(5) Thermal design
Use a thermal design that a llows for a sufficient margin in l ight of the power dissipation (Pd) in actual operati ng conditions.
(6) Off-leakage at high temperature.
Off-leakage at high temperature may increase because of manufacturing variations.
Design should consider the typical & worst cases shown below.
(7) Inter-pin shorts and mountin g error s
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection err or or if pins ar e short ed toget h er.
(8) Actions in stron g electromagn etic fie ld
Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to
malfunction.
(9) ASO
When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO.
(10) Thermal shutdow n circuit
The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is
designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its operation.
Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circuit
is assumed.

(11) Testing on application boards
When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress.
Always discharge capacitors after each process or step. Always turn the ICs power supply off before connecting it to or
removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic
measure. Use similar precaution when transporting or storing the IC.
(12) Regarding input pin of the IC
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, creating a parasitic
diode or transistor. For example, the relation between each potential is as follows:
When GND > Pin A and GND > Pin B, the P-N juncti on operates as a paras iti c diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes
operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used.
(13) Ground Wiring Pattern.
When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns,
placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage
variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change
the GND wi ring pattern of any external components, either.

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe d esign against the physical injur y, damage to any property, which
a failure or malfunction of our Products may cause. T he following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3. Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-produci ng comp onents, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flu x (even if you use no-clean type fluxes, cleaning residue of
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
residue after soldering
[h] Use of the Products in places subject to dew condensation
4. The Products are not subject to radi ation-proof design.
5. Please verify and confirm characteristics of the final or mounted products in using the Products.
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding nor mal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7. De-rate Power Dissipation (Pd) depending o n Ambient temper ature (Ta). When us ed in se aled area, confirm the actual
ambient temperature.
8. Confirm that operation temperature is within the specifi ed range described in the product specification.
9. ROHM shall not be in any way responsible or lia ble for failure induced under deviant conditio n from what is defined in
this document.
Precaution for Mounting / Circuit board design
1. When a highly active halogen ous (chlori ne, bromine, etc.) flu x is used, the residue of flux may negativel y affect product
performance and reliability.
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
