EMP8020-28VF05NRR fiche technique
ESMT/EMP
Preliminary
EMP8020
Fast Ultra High-PSRR, Low-Noise, Low-Dropout,
300mA CMOS Linear Regulator
General Description
The EMP8020 low-dropout (LDO) CMOS linear regulator
features an ultra-high power supply rejection ratio (78dB
at 1kHz), low output voltage noise (48µV), low dropout
voltage, low quiescent current (50µA), and fast
transient response. It guarantees a delivery of 300mA
output current, and supports preset output voltages
ranging from 0.8V to 4.75V with 0.05V increments.
The EMP8020 is ideal for battery-powered applications
because of its low quiescent current consumption and
its 1nA shutdown mode. The regulator 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
EMP8020 holds well for low input voltages typically
encountered in battery operated systems. The regulator
is stable with small ceramic capacitive loads (2.2µF
typical).
Additional features include bandgap voltage
reference, constant current limiting, and thermal
overload protection. Both of Miniature 5-pin
SC-70-5/SOT-23-5 and 4-pin SC-82-4 package options
are offered to provide flexibility for different
applications.
