Automobile-voltage-regulator


Posted on Oct 6, 2012

A monolithic 555-type timer is the heart of this simple automobile voltage regulator. When the timer is off so that its output at pin 3 is low, the power Darlington transistor pair is off. If battery voltage becomes too low, less than 14.4 V in this case, the timer turns on and the Darlington pair conducts. Can be any general purpose Silicon diode or 1 N4157 device.
