ESMT/EMP
EMP891X
Fast Ultra High-PSRR, Low-Noise, Low-Dropout,
150mA Micropower CMOS Linear Regulator
General Description
The EMP891X series is a family of CMOS linear regulators,
which include EMP8915 and EMP8916, featuring
ultra-high power supply rejection ratio, low output
voltage noise, low dropout voltage, low quiescent
current and fast transient response. EMP891X
guarantees delivery of 150mA output current, and
supports preset 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 2.8V, 2.85V
output voltage versions.
Based on its low quiescent current consumption and its
less than 1μA shutdown mode of logical operation, the
EMP891X series are ideal for battery-powered
applications. The ground current increases only slightly
in dropout, further prolonging the battery life.
EMP891X series provide fast turn-on 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 EMP891X 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. Available in miniature
SOT-25, SOT-26 and TDFN-6 packages, the EMP891X
series are suitable for portable appliances.
EMP products is RoHS compliant.
