GENERAL DESCRIPTION

The ADM7160 is an ultralow noise, low dropout linear regulator that operates from 2.2 V to 5.5 V and provides up to 200 mA of output current. The low 150 mV dropout voltage at 200 mA load improves efficiency and allows operation over a wide input voltage range.

FEATURES

PSRR performance of 54 dB at 100 kHz

Ultralow noise independent of VOUT

3 µV rms, 0.1 Hz to 10 Hz

9.5 µV rms, 0.1 Hz to 100 kHz

9 µV rms, 10 Hz to 100 kHz

17 µV rms, 10 Hz to 1 MHz

Low dropout voltage: 150 mV at 200 mA load

Maximum output current: 200 mA

Input voltage range: 2.2 V to 5.5 V
