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

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.
