17V, 5V / 0.5A Low Dropout
Voltage Regulator
Overview
The L88M05T is low dropout voltage regulator IC 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.
Functions
• Output voltage : 5V
• 500 mA output current
• Low minimum input-output voltage differential (0.4V 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.

Notes: 1. To ensure operational stability, CIN and COUT should be placed as close to the IC as possible.
2. 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).
3. When VIN is minus (–) and GND is plus (+) (reversed connection), excessive current flow will occur.

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.
