LOW DROPOUT VOLTAGE REGULATORS March 1993 OUTPUT VOLTAGE OF 5, 8.5 AND 10 V OUTPUT CURRENT UP TO 500 mA NO EXTERNAL COMPONENTS LOW DROP OUT VOLTAGE OVERVOLTAGE PROTECTION ( ± 100V) REVERSE VOLTAGE PROTECTION SHORT CIRCUIT PROTECTION CURRENT LIMITING THERMAL SHUTDOWN

DESCRIPTION

The L2600 series og three terminal positive regu- lators is specially designed to stabilize power sup- plies car instrumentation in vehicles with 12V battery. Available with output voltages equal to 5V,

8.5 V, 10V, they can supply an output current to

500mA. These devices are protected against load dump and field decay transients (±100V), reverse battery, short circuit and thermal overload. Order codes Output Voltage TO-220 SOT-82 L2605V L2605X 5 V L2685V L2685X 8.5 V L2610V L2610X 10 V BLOCK DIAGRAM TO-220 SOT-82
