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.
Features
