SJ2148

1.5A CMOS

Low Dropout Voltage Regulator

RoHS Compliant Product

Description

The SJ2148 series of positive,linear regulators feature low quiescent

current (45µA typ.) with low dropout voltage, making them ideal

for battery applications.These rugged devices have bothThermal

Shutdown and Current Fold-back to prevent device failure under

the "Worst" of operating conditions.The SJ 2148 is stable with an

output capacitance of 4.7µF or greater.

Features
