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.
