ESMT
Preliminary
EMP8731
High-PSRR, Low-Noise, 300mA CMOS Linear
Regulator with 3 Types of Output Select
General Description
The EMP8731 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 3 types of output
voltages via ADJ pin.
Based on its low quiescent current consumption and
its less than 1µA shutdown mode of logical operation,
the EMP8731 is ideal for battery-powered
applications. The high power supply rejection ratio
of the EMP8731 holds well for low input voltages
typically encountered in battery-operated systems.
The regulator is stable with small ceramic capacitive
loads (2.2µF typical). The EMP8731 is available in
miniature SOT-23-5 packages.
