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.
