EMP893X
EMP893X is 300mA Micropower CMOS Linear Regulator manufactured by Elite Semiconductor Microelectronics Technology.
Description
The EMP893X series is a family of CMOS linear regulators. It is consisted of EMP8935, EMP8936 and EMP8938, featuring ultra-high power supply rejection ratio, low output voltage noise, low dropout voltage, low quiescent current and fast transient response. It guarantees delivery of 300m A output current, and supports preset 1.2V, 1.5V, 1.8V, 2.5V, 2.7V, 2.8V, 3.0V, 3.3V output voltage versions.

- - Based on its low quiescent current consumption and its less than 1μA shutdown mode of logical operation, the EMP893X is ideal for battery-powered applications. It provides fast turn-on and start-up time by using dedicated circuitry to pre-charge an optional external bypass capacitor. This bypass capacitor is used to reduce the output voltage noise without adversely affecting the load transient response. The high power supply rejection ratio of the EMP893X holds well for low input voltages typically encountered in battery-
