NCP103
150 mA CMOS Low Dropout
Regulator
The NCP103 is 150 mA LDO that provides the engineer with a very
stable, accurate voltage with low noise suitable for space constrained,
noise sensitive applications. In order to optimize performance for
battery operated portable applications, the NCP103 employs the
dynamic quiescent current adjustment for very low I
Q
consumption at
no−load.

Description
Regulated output voltage pin. A small ceramic capacitor with minimum value of 1
mF
is needed from this
pin to ground to assure stability.
Power supply ground.
Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown
mode.
Input pin. A small capacitor is needed from this pin to ground to assure stability.
Exposed pad should be connected directly to the GND pin. Soldered to a large ground copper plane allows
for effective heat removal.
