EMP5523
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 300m A 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 170m V low dropout voltage at 300m A output current, EMP5523 sustains high PSRR at very low input voltage which is mon in battery-powered application. The EMP5523 also features
120µVRMS low output voltage noise without the presence of a noise bypass capacitor, which fits the application where noise and board space are both concerned. Other features include thermal protection and over-current protection. The EMP5523 is available in SOP-8...
