Monolithic Linear IC
L88MS00T Series
4 to 12 V, 0.5 A Low Dropout Voltage
Regulator with On/Off Function
Overview
Package Dimensions
unit : mm
The L88MS00T Series has 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.

Output voltage L88MS04T: 4 V L88MS05T: 5 V
L88MS06T: 6 V L88MS08T: 8 V
L88MS09T: 9 V L88MS12T: 12 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 (L88MS05T/IQ OFF
= 40 µA typ, except ISTB).
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.
