1.3V Power supply


Posted on Feb 6, 2014

This 1. 3V power supply can be used as replacement for the 1. 3V Mercury Cell in any circuit. When the input 5V is given to the circuit, the voltage drop across zener diode D1 will be around 2V. The diode D2 will drop a 0. 7 V from the 2V volt and the remaining 1. 3V will be available at the output. The Resistor R1 limits the current through Zener diod
