NCV8114
300 mA CMOS Low Dropout
Regulator
The NCV8114 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 NCV8114
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.
Not connected. This pin can be tied to ground to improve thermal dissipation.
