Microsemi’s

regulator ICs using CMOS technology. The

device provides a compact and cost effective

solution featuring low power consumption

over a wide supply voltage range, high output

voltage accuracy, low dropout, excellent line

and load regulation, fast transient response,

and low noise.

voltage range of 2.5V to 6V, and consumes

only 60uA typical quiescent current at no load

and a low 0.1uA shutdown current. Output

voltage options include fixed 1.2V, 3.3V, or

an adjustable output voltage which may be

set from 1.2V to 5.5V. The LDO delivers up

to 300mA of output current, with a foldback

current limit of approximately 400mA.

300mA load, dropout voltage measures only

170mV for a 3.3V output.

over the full output current and supply range.

The high bandwidth control loop provides fast

transient response to reduce output voltage

deviation using low cost external ceramic

capacitors in the 1uF range.
