L88MS33T
3.3 V, 0.5 A Low Dropout Voltage Regulator
with On/Off Function
Overview
The L88MS33T is a low dropout voltage regulator with an
output voltage of 3.3 V (standard), with an on-chip on/off
function to maximize equipment power saving effectiveness.
Because it can operate with a low input-output voltage
difference, it contributes to smaller and more efficient set
power supplies, optimum for audio-visual and office
automation equipment.

Functions
. _{Output voltage: 3.3 V}
. _{On/off control of output voltage by strobe pin (active low)}
. _{500 mA output current}
Features
. _{Low minimum input-output voltage differential (0.4 V typ)}
enables to save energy and miniaturize transformer size.
. _{Quiescent current is low with output off.}
. _{Set size can be miniaturized with compact TP-5H power}
. ^package.
Surface mounting on board permits allowable power
dissipation to be raised.
. _{Enhanced mount flexibility with range of formed products.}
. _{On-chip protective circuitry (fold back short circuit, thermal}
. ^{over load).}
External noise suppression pin provided.
