RoHS Compliant Product

Description

The SQ2181 of positive, linear requlator feature low quiescent current (50 µA

typ.) with low dropout voltage and excellent PSRR, thus making them ideal for

for Telecommunications and other battery applications. These rugged devices

have both Thermal Shutdown, and Current Fold-back to prevent device failure

under the "Worst" ofoperating conditions. As an additional feature, the SQ2181

is stable

with an output capacitance of 2.2µF or greater.

Features

* Over-Temperature Shutdown

* Excellent PSRR Type 70 dB

* Very Low Dropout Voltage

* Factor Pre-set Output Voltage

* Short Circuit Current Fold-back

* Guaranteed 150mA output

* Current Limiting
