APL5151/2/3/4
Low IQ, Low Dropout 150mA Fixed Voltage Regulator
Features
General Description
•
Low Noise: 60uVRMS (100Hz to 100kHz)
The APL5151/2/3/4 is micropower, low noise, low
•
Low Quiescent Current: 50uA
•
Low Dropout Voltage: 300mV
dropout linear regulator. Operate from 3V to 6V input
voltage and deliver up to 150mA. Typical output noise
is just 60uVRMS with the addition of an external 0.33uF
(VOUT(Nominal) = 3.0V Version @150mA)
bypass capacitor in BP pin and typical dropout voltage
•
Very low Shutdown Current: < 0.5uA
is only 220mV at 150mA loading. Designed for use in
