Monolithic Linear IC
L88M00T Series
3.3 to 12 V, 0.5 A Low Dropout
Voltage Regulator
Overview
The L88M00T Series are low dropout voltage regulator ICs
with output current of 0.5 A. Because they can operate with a
low input-output voltage difference, they contribute to smaller
and more efficient set power supplies, and are optimum for
audio-visual and office automation equipment.

[L88M00T Series]
Functions and Features
. Output voltage L88M33T: 3.3 V L88M05T: 5 V
L88M09T: 9 V L88M12T: 12 V
. 500 mA output current
. Low minimum input-output voltage differential (0.4 V typ)
. enables to save energy and miniaturize transformer size.
Set size can be miniaturized with compact TP-3H power
. package.
Surface mounting on board permits allowable power
. dissipation to be raised.
Enhanced mount flexibility with range of formed products.

1) 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.

2) Pd is the value for when the solder on the surface of the IC heat sink has melted completely and the surface mount is
horizontal.
3) Please be advised that the flow solder application system (full-heat method) cannot be recommended.
