| L2605 L2685-L2610 LOW DROPOUT VOLTAGE REGULATORS s s s s s s s s s 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 TO-220 DESCRIPTION The L2600 series og three terminal positive regulators is specially designed to stabilize power supplies 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.
