Understanding 7805 IC Voltage Regulator
A regulated power supply is very much essential for several electronic devices due to the semiconductor material employed
in them have a fixed rate of current as well as voltage. The device may get damaged if there is any deviation from the fixed
rate. The AC power supply gets converted into constant DC by this circuit. By the help of a voltage regulator DC,
unregulated output will be fixed to a constant voltage. The circuit is made up of linear voltage regulator 7805 along with
capacitors and resistors with bridge rectifier made up from diodes. From giving an unchanging voltage supply to building
confident that output reaches uninterrupted to the appliance, the diodes along with capacitors handle elevated efficient
signal conveyal.
Description:
As we have previously talked about that regulated power supply is a device that mechanized on DC voltages and also it can
uphold its output accurately at a fixed voltage all the time although if there is a significant alteration in the DC input voltage.
ICs regulator is mainly used in the circuit to maintain the exact voltage which is followed by the power supply. A regulator is
mainly employed with the capacitor connected in parallel to the input terminal and the output terminal of the IC regulator. For
the checking of gigantic alterations in the input as well as in the output filter, capacitors are used. While the bypass
capacitors are used to check the small period spikes on the input and output level. Bypass capacitors are mainly of small
values that are used to bypass the small period pulses straightly into the Earth.
A circuit diagram having regulator IC and all the above discussed components arrangement revealed in the figure below.

The working of the components coupled in the circuit above is revealed in the following table:
Component
Function
C1 This capacitor is known as bypass capacitor and is employed to bypass extremely tiny duration
spikes to the ground with no distress the other components.
C2 C2 is the filter capacitor employed to steady the slow changes in the voltage applied at the input of
the circuit. Escalating the value of the capacitor amplify the stabilization as well as the declining
