EMP8130-Ultra High-PSRR, Low-Noise, 300mA CMOS Linear Regulator DataSheet
The EMP8130 features ultra-high power supply rejection ratio, low output voltage noise, low dropout voltage, low quiescent current and fast transient response. It guarantees delivery of 300mA output current and supports preset output voltages ranging from 0.8V to 4.0V with 0.1V increment.
Based on its low quiescent current consumption and its less than 1uA shutdown mode of logical operation,the EMP8130 is ideal for battery-powered applications. The high power supply rejection ratio of the EMP8130 holds well for low input voltages typically encountered in battery-operated systems. The regulator is stable with small ceramic capacitive loads (1μF typical).
The EMP8130 is available in miniature SOT-23-5 package.
