DEFINITIONS
Load Regulation
The change in output voltage for a change in output load
current at a constant temperature.
Dropout Voltage
The input/output differential at which the regulator output
no longer maintains regulation against further reductions in
input voltage. Measured when the output drops 2% below its
nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
Output Noise Voltage
This is the integrated value of the output noise over a
specified frequency range. Input voltage and output load
current are kept constant during the measurement. Results
are expressed in mVrms or nV Hz.
Ground Current
Ground Current is the current that flows through the
ground pin when the regulator operates without a load on its
output (IGND). This consists of internal IC operation, bias,
etc. It is actually the difference between the input current
(measured through the LDO input pin) and the output load
current. If the regulator has an input pin that reduces its
internal bias and shuts off the output (enable/disable
function), this term is called the standby current (ISTBY
.)
Line Regulation
The change in output voltage for a change in input voltage.
The measurement is made under conditions of low
dissipation or by using pulse techniques such that the
average junction temperature is not significantly affected.
Line Transient Response
Typical output voltage overshoot and undershoot
response when the input voltage is excited with a given
slope.
Load Transient Response
Typical output voltage overshoot and undershoot
response when the output current is excited with a given
slope between noload and fullload conditions.
Thermal Protection
Internal thermal shutdown circuitry is provided to protect
the integrated circuit in the event that the maximum junction
temperature is exceeded. When activated at typically 175°C,
the regulator turns off. This feature is provided to prevent
failures from accidental overheating.
Maximum Package Power Dissipation
The power dissipation level at which the junction
temperature reaches its maximum operating value.
APPLICATIONS INFORMATION
The NCP603 series regulator is selfprotected with
internal thermal shutdown and internal current limit. Typical
application circuits are shown in Figures 2 and 3.
Input Decoupling (Cin)
A ceramic or tantalum 1.0 mF capacitor is recommended
and should be connected close to the NCP603 package.
Higher capacitance and lower ESR will improve the overall
line transient response.
Output Decoupling (Cout)
The NCP603 is a stable component and does not require
a minimum Equivalent Series Resistance (ESR) for the
output capacitor. The minimum output decoupling value is
1.0 mF and can be augmented to fulfill stringent load
transient requirements. The regulator works with ceramic
chip capacitors as well as tantalum devices. Larger values
improve noise rejection and load regulation transient
response. Figure 28 shows the stability region for a range of
operating conditions and ESR values.
NoLoad Regulation Considerations
The NCP603 adjustable regulator will operate properly
under conditions where the only load current is through the
resistor divider that sets the output voltage. However, in the
case where the NCP603 is configured to provide a 1.250 V
output, there is no resistor divider. If the part is enabled
under noload conditions, leakage current through the pass
transistor at junction temperatures above 85°C can approach
several microamperes, especially as junction temperature
approaches 150°C. If this leakage current is not directed into
a load, the output voltage will rise up to a level
approximately 20 mV above nominal.
The NCP603 contains an overshoot clamp circuit to
improve transient response during a load current step
release. When output voltage exceeds the nominal by
approximately 20 mV, this circuit becomes active and
clamps the output from further voltage increase. Tying the
ENABLE pin to Vin will ensure that the part is active
whenever the supply voltage is present, thus guaranteeing
that the clamp circuit is active whenever leakage current is
present.
When the NCP603 adjustable regulator is disabled, the
overshoot clamp circuit becomes inactive and the pass
transistor leakage will charge any capacitance on Vout. If no
load is present, the output can charge up to within a few
millivolts of Vin. In most applications, the load will present
some impedance to Vout such that the output voltage will be
inherently clamped at a safe level. A minimum load of
10 mA is recommended.

Noise Decoupling
The NCP603 is a low noise regulator and needs no
external noise reduction capacitor. Unlike other low noise
regulators which require an external capacitor and have slow
startup times, the NCP603 operates without a noise
reduction capacitor, has a typical 15 ms start up delay and
achieves a 50 mVrms overall noise level between 10 Hz and
100 kHz.
Enable Operation
The enable pin will turn the regulator on or off. The
threshold limits are covered in the electrical characteristics
table in this data sheet. The turnon/turnoff transient
voltage being supplied to the enable pin should exceed a
slew rate of 10 mV/ms to ensure correct operation. If the
enable function is not to be used then the pin should be
connected to Vin.
Output Voltage Adjust
The output voltage can be adjusted from 1 times
(Figure 2) to 4 times (Figure 3) the typical 1.250 V
regulation voltage via the use of resistors between the output
and the ADJ input. The output voltage and resistors are
chosen using Equation 1 and Equation 2.
VOUT +1.250 ǒ1)R1
R2Ǔ)(IADJ R1) (eq. 1)
R1 +R2 * ƪ[Vout *(IADJ *R1)]
1.25 *1ƫ^R2 ƪVout
1.25 *1ƫ
(eq. 2)
Input bias current IADJ is typically less than 150 nA.
Choose R2 arbitrarily t minimize errors due to the bias
current and to minimize noise contribution to the output
voltage. Use Equation 2 to find the required value for R1.
Thermal
As power in the NCP603 increases, it might become
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design and layout. Mounting pad configuration
on the PCB, the board material, and the ambient temperature
affect the rate of junction temperature rise for the part. When
the NCP603 has good thermal conductivity through the
PCB, the junction temperature will be relatively low with
high power applications. The maximum dissipation the
NCP603 can handle is given by:
PD(MAX) +TJ(MAX) *TA
RqJA (eq. 3)
Since TJ is not recommended to exceed 125_C (TJ(MAX)),
then the NCP603 can dissipate up to 465 mW when the
ambient temperature (TA) is 25_C and the device is
assembled on 1 oz PCB with 645 mm2 area.
The power dissipated by the NCP603 can be calculated
from the following equations:
PD[VIN(IGND@IOUT))IOUT(VIN *VOUT)
(eq. 4)
or
VIN(MAX) [PD(MAX) )(VOUT IOUT)
IOUT )IGND (eq. 5)
Hints
Vin and GND printed circuit board traces should be as
wide as possible. When the impedance of these traces is
high, there is a chance to pick up noise or cause the regulator
to malfunction. Place external components, especially the
output capacitor, as close as possible to the NCP603, and
make traces as short as possible.
