Ordering number: EN5839
Monolithic Linear IC
L88M00T Series
3.3 to 12 V, 0.5 A Low Dropout
Voltage Regulator
Overview
Package Dimensions
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.

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.

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.
