This is a simple design of power supply that can be used as replacement for the 1.3V Mercury Cell in any circuit. This component for the circuit is only need some component like resistor, capacitor, diode. This is a figure for the circuit.
The operation of the circuit is 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 diode. There are some attention for the circuit. The circuit can be assembled on a general purpose board. This power supply is suitable for measurement devices like digital multi meters, digital clocks, digital thermometers etc. The zener diode D1 can be a 2V one like BZX552V0.
