EMP2133
Description
The EMP2133 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 EMP2133 is well suited for portable battery-powered application which requires high efficiency, low noise and small board space. With 130m V low dropout voltage at 300m A output current, EMP2133 sustains high PSRR at very low input voltage which is mon in battery-powered application. The EMP2133 also features
110µVRMS low output voltage noise without the presence of a noise bypass capacitor, which fits the application where noise and board space are both concerned. Each regulator in the EMP2133 can be turned off independently, further prolonging the battery life. Internally...
