DESCRIPTION

The L2600 series og three terminal positive regu­latorsis speciallydesigned to stabilizepower sup­plies car instrumentation in vehicles with 12V
battery. Availablewith outputvoltages equal to 5V,

8.5 V, 10V, they can supply an output current to
500mA.

These devices are protected against load dump
andfielddecay transients(±100V),reversebattery,
shortcircuit and thermal overload.
