Ordering number : EN5839C L88M05T Monolithic Linear IC 17V, 5V / 0.5A Low Dropout Voltage Regulator http://onsemi.com 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.

No.5839-3/8 L88M00T Series Reference voltage Start-up circuit Equivalent Circuit Block Diagram (Common to L88M00T Series) Error amp Short circuit protector Thermal protector Test Circuit (Common to L88M00T Series) L88M00T 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.
