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
    Low quiescent and shutdown current
    Initial accuracy: ±1%
    Accuracy over line, load, and temperature: −2.5%/+1.5%
    5-lead TSOT package and 6-lead LFCSP package

APPLICATIONS
    ADC/DAC power supplies
    RF, VCO, and PLL power supplies
    Post dc-to-dc regulation
