LD501 - CMOS Linear Regulator

Datasheet Summary

Description

The LD501 is an ultra-low noise, low dropout (LDO) linear regulator that operates from 2.2V to 5.5V and provides output current up to 150mA (LD501L), 200mA (LD501M), or 250mA (LD501P).

70mV at 150mA load (LD501L), 94mV at 200mA load (LD501M), or 118mV at 250mA load (L

Features

Ultra-low noise: 13.5μV rms at VOUT = 3.3V 9.5µV rms at VOUT = 1.1V.
No noise bypass capacitor required.
Stable with 1μF ceramic input and output capacitors.
Maximum output current: 150mA (LD501L) 200mA (LD501M) 250mA (LD501P).
Input voltage range: 2.2V to 5.5V.
Low quiescent current IGND = 12μA with IOUT = 0mA IGND = 170μA with IOUT = 150mA (LD501L) IGND = 200μA with IOUT = 200mA (LD501M) IGND = 229μA with IOUT = 250mA (LD501P).
