General Description

The 300 mA, adjustable dual output ADP223/ADP225 and fixed dual output ADP222/ADP224 combine high PSRR, low noise, low quiescent current, and low dropout voltage in a voltage regulator that is ideally suited for wireless applications with demanding performance and board space requirements.

The ADP222/ADP224 are available with fixed outputs voltages from 0.8V to 3.3V.

The adjustable output ADP223/ADP225 may be set to output voltages from 0.5 V to 5.0 V.
