EMP8734
Fast Ultra High-PSRR, Low-Noise, 300mA
CMOS Linear Regulator
General Description
The EMP8734 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
4.5V with 0.05V increment.
Based on its low quiescent current consumption and its
less than 1μA shutdown mode of logical operation, the
EMP8734 is ideal for battery-powered applications. The
high power supply rejection ratio of the EMP8734 holds
well for low input voltages typically encountered in
battery-operated systems. The regulator is stable with
small ceramic capacitive loads (1µF typical). The
EMP8734 is Available in miniature SOT-23-5
SOT-353(SC-70-5 ), SOT-343 and TDFN-6 packages.
