ESMT/EMP
CMOS Linear Regulator
General Description
The EMP5523 series is a family of dual-channel CMOS linear regulators featuring ultra-high power supply rejection ratio (PSRR), low output voltage noise, low dropout voltage, low quiescent current and fast transient response. It guarantees delivery of 300mA output current per regulator, and supports preset output voltages ranging from 1.2V to 3.3V with 0.1V increment (except for 1.85V and 2.85V). The EMP5523 is well suited for portable battery-powered application which requires high efficiency, low noise and small board space. With 170mV low dropout voltage at 300mA output current, EMP5523 sustains high PSRR at very low input voltage which is common in battery-powered application.
