APPLICATIONS INFORMATION
The NCP164 is the member of new family of high output
current and low dropout regulators which delivers low
quiescent and ground current consumption, good noise and
power supply ripple rejection ratio performance. The
NCP164 incorporates EN pin and power good output for
simple controlling by MCU or logic. Standard features
include current limiting, soft−start feature and thermal
protection.
saturation voltage. External pull−up resistor can be
connected to any voltage up to 5.0 V (please see Absolute
Maximum Ratings table).
Power Dissipation and Heat Sinking
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. For reliable operation junction temperature
should be limited to +125°C, however device is capable to
work up to junction temperature +150°C. The maximum
power dissipation the NCP164 can handle is given by:
Input Decoupling (CIN)
It is recommended to connect at least 1 mF ceramic X5R
or X7R capacitor between IN and GND pin of the device.
This capacitor will provide a low impedance path for any
unwanted AC signals or noise superimposed onto constant
input voltage. The good input capacitor will limit the
influence of input trace inductances and source resistance
during sudden load current changes. Higher capacitance and
lower ESR capacitors will improve the overall line transient
response.

The power dissipated by the NCP164 for given
application conditions can be calculated from the following
equations:

or
The NCP164 does not require a minimum Equivalent
Series Resistance (ESR) for the output capacitor. The device
is designed to be stable with standard ceramics capacitors
with values of 1 mF or greater. The X5R and X7R types have
the lowest capacitance variations over temperature thus they
are recommended.

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 NCP164, and
make traces as short as possible.
Power Good Output Connection
The NCP164 include Power Good functionality for better
interfacing to MCU system. Power Good output is open
collector type, capable to sink up to 10 mA. Recommended
operating current is between 10 mA and 1 mA to obtain low

Not only adjustable version, but also any fixed version can
be used to create adjustable voltage, where original fixed
voltage becomes reference voltage for resistor divider and
feedback loop. Output voltage can be equal or higher than

the device at output voltage about 5.2 V, as device can be
damaged.
In order to avoid influence of current flowing into SNS pin
to output voltage accuracy (SNS current varies with voltage
option and temperature, typical value is 300 nA) it is
recommended to use values of R1 and R2 below 500 kW.
