Sanyo L88M00T_SERIES Specifications

Ordering number: EN5839

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.

Functions and Features

.

Output voltage L88M33T: 3.3 V L88M05T: 5 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.

Notes: 1. To ensure operational stability, CINand C

2. Because the output capacitor C
exhibits little change in capacity with temperature variations should be used (such as a tantalum capacitor).

3. When V
