EMP8130-Ultra High-PSRR, Low-Noise, 300mA CMOS Linear Regulator DataSheet

General Description
    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 .
    The EMP8130 is available in miniature SOT-23-5,
uDFN-4, SC-70-5, SC-82-4, TSOT-23-5, SOT-23-3 and
TDFN-6 package.
