SEMP8965
Fast Ultra High-PSRR, Low Noise, Low-Dropout,
600 mA Micropower CMOS Linear Regulator
RoHS Compliant Product
A suffix of “-C” specifies halogen or lead -free
DESCRIPTION
The SEMP8965 low-dropout (LDO) CMOS linear regulators, consisting of SEMP8965, SEMP8966, and SEMP8968,
feature ultra-high power supply rejection ratio (75dB at 1kHz), low output voltage noise (30µV), low dropout voltage
(270mV), low quiescent current (110µA), and fast transient response. It guarantees delivery of 600mA output current,
and supports preset (1.2V~3.3V with 0.1V increment, except for 1.85V and 2.85V) as well as adjustable (1.2V to 5.0V)
output voltage versions.
The SEMP8965 is ideal for battery-powered applications by virtue of its low quiescent current consumption and its
1nA shutdown mode of logical operation. 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 SEMP8965
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, band-gap voltage reference, constant current limiting and
thermal overload protection.
