NCP114
300 mA CMOS Low Dropout
Regulator
The NCP114 is 300 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 NCP114 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 need-
ed 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.
Not connected. This pin can be tied to ground to improve thermal dissipation.
Exposed pad should be connected directly to the GND pin. Soldered to a large ground cop-
per plane allows for effective heat removal.
