8v fixed 1A positive power supply regulator.
This is a simple power supply circuit diagram. In this circuit, an input voltage of 10.5V to 23V can be used, with a fixed output voltage of 7.7V to 8.3V. This power supply can drive 8V, 1amp, and 15 watt devices. It can be used as a 15 watt electronic device. This power supply uses a voltage regulator lm7808 IC. DC to DC voltage can be converted through this circuit. This is called a stop-down power supply.

The capacitor is a Two-Terminal detached part having the Property of Capacitance This Property Zaps (accusing of power) Capacitors with input Voltage. Capacitors Gather Power, Thus it is otherwise called a Condenser. It comprises two Electrical Conveyors that are Isolated by Distance. The Capacitor Stores Charge and can carry on like a Battery. It is fundamental for channel Circuits to Limit voltage spikes, and Smoothing changes in voltage.
A voltage regulator is an integrated circuit (IC). The voltage regulator provides constant output voltage even if its load or input voltage changes.LM7808 is a monolithic 3-terminal positive voltage regulator. It provides a fixed regulated output of 7.75v- 8.25V DC for a variable input voltage range of 10.5V to 23V DC. The maximum output current is 1 A. The dropout voltage of LM7808 is 2V. LM7808 IC is in compact packaging with 3 pins for positive input voltage/positive output voltage and ground pin. It has internal thermal shutdown, short-circuit and SOA protection, and an output capacitance of 0.5 pF.
