How to make a fixed 5V voltage DC power supply | Power supply

5v fixed 1A positive power supply regulator-use as a mobile charger.

This is a simple power supply circuit diagram. In this circuit, an input voltage of 7V to 20V can be used, with a fixed output voltage of 4.75V to 5.25V. This power supply can drive 5V, 1amp, and 15-watt devices. It can be used as a 15 watt mobile charger. This power supply uses a voltage regulator lm7805 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.LM7805 is a monolithic 3-terminal positive voltage regulator. LM7805 has an input voltage of 7V to 20v and an output voltage of 4.8v to 5.2v constant. The maximum output current is 1A. It has internal thermal shutdown, short-circuit and SOA protection, and an output capacitance of 0.5 pF. A voltage regulator is an integrated circuit (IC). The voltage regulator provides constant output voltage even if its load or input voltage changes. This prevents excess Voltage From Destroying and Overheating the Voltage Regulator Since the Heat Sink Dissipates the Excess Power as heat. A heat Sink Should be Attached to a Voltage Regulator to dissipate Excess Power that may Enter into The Regulator.
