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.
