EMP893X
Fast Ultra High-PSRR, Low-Noise, Low-Dropout,
300mA Micropower CMOS Linear Regulator
General Description
The EMP893X series is a family of CMOS linear regulators.
It is consisted of EMP8935, EMP8936 and EMP8938,
featuring 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 1.2V, 1.5V, 1.8V, 2.5V, 2.7V, 2.8V, 3.0V,
3.3V output voltage versions.
Based on its low quiescent current consumption and its
less than 1μA shutdown mode of logical operation, the
EMP893X is ideal for battery-powered applications. It
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 EMP893X 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 regulation fault detection,
bandgap voltage reference, constant current limiting
and thermal overload protection. The EMP893X is
Available in miniature SOT-23-5, SOT-23-6, TDFN-6 and
MSOP-8 packages.
EMP products is RoHS compliant.
