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.

Functions
.
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.

Test Circuit (Common to L88MS00T Series)
L88MS00T
Notes: 1. Because the output capacitor COUT is set at over 100 µF to prevent oscillation at low temperatures, a capacitor that
exhibits little change in capacity with temperature variations should be used (such as a tantalum capacitor).
2. Adding capacitor Cn enables external noise suppression and ripple rejection to be improved. However, attention should
be given to system stability (phase margin).
3. To ensure operational stability, CIN, COUT, and Cn should be placed as close to the IC as possible.
4. When the strobe (STB) pin is open, output is turned on by internal bias. When the strobe function is not used, the STB
pin should be connected to GND to complete strobe operation.
5. When VIN is minus (–) and GND is plus (+) (reversed connection), excessive current flow will occur.

Adjustment of output voltage VOUT
(1) Reducing VOUT
VOUT can be lowered by externally connecting a resistor
RA between the Cn and VOUT pins.
(2) Increasing VOUT
VOUT can be raised by externally connecting a resistor RB
between the Cn and GND pins.

The allowable power dissipation is 1.0 W (Ta = 25°C) with no fin attached, but when mounted on a hybrid IC board or printed
circuit board, high allowable power dissipation is achieved, despite the compact package. The graph below depicts the relationship
between the copper-clad area and allowable power dissipation when mounted on a glass epoxy board (50 × 5 0 × 0.8 tmm3) with a
copper thickness of 18 µm.
