NCP4586/D
NCP4586
150 mA, Low Noise, Low
Dropout Regulator
The NCP4586 is a CMOS 150 mA low dropout linear with low
noise, high ripple rejection, low dropout, high output voltage accuracy
and low supply current. The device is available in three
configurations: enable high, enable low and enable high plus
auto−discharge. Small packages allow mounting on high density
PCBs. This is an excellent general purpose regulator, well suited to
many applications.
