It will keep a stable voltage when it has any load.
Regulated power supply circuit diagram.
In the above diagram we can see how an ordinary 7805 regulator ic could be used for creating a fixed 5v regulated output.
Circuit diagram 5v power supply circuit using 7805 voltage regulator.
Regulated power supply block diagram a regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure.
Datasheet of 7805 prescribes to use a 0 01μf capacitor at the output side to avoid transient changes in the voltages due to changes in load and a 0 33μf at the input side of regulator to avoid ripples if the filtering is far away from regulator.
The block diagram of a regulated power supply mainly includes a step down transformer a rectifier a dc filter and a regulator.
But it still has the same characteristics as a fixed regulated power supply.
Making a fixed 12v regulator circuit.
Regulated power supply block diagram transformer and ac supply.
In case you wanted to achieve a fixed 12v regulated power supply the same configuration could be applied for getting the required results as shown below.
Adjustable power supply circuit.
The output from an ordinary power supply is fed to the voltage regulating device that provides the final output.
Transistor variable power supply 1a 0 30v.
A regulated dc power supply is also known as a linear power supply it is an embedded circuit and consists of various blocks.
The construction working of a regulated power supply is discussed below.
