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.
