TS1123

Ultra Low Dropout Voltage Regulator Driver

with Enable Function

1/4

Version: B07

SOT-25

General Description

TS1123 is a low dropout voltage regulator driver for various electronic equipments. It provides constant voltage power

source with SOT-25 package. TS1123 with external PNP transistor can drive output current up to 4A, quiescent

current is typically at 5mA. Further more, the quiescent current is smaller when the regulator is in the dropout mode

function.
