Block Diagram Voltage Regulator

The functional block diagram of ic 723 voltage regulator can be divided into four major blocks temperature compensated voltage reference source which is zener diode.
Block diagram voltage regulator. The unregulated ac voltage is connected to a transformer which steps that ac voltage down to the level for the desired dc output. The control element shunts a part of the current that is produced as a result of the input unregulated voltage that is given to the load. As the name says the voltage regulation is provided by shunting the current away from the load. A series pass transistor capable of a 150 ma output current.
Block diagram and circuits in the video will help you to makeitclear about ic723 in brief and also its role in voltage regulation gate 2018 eee books 1. The block diagram of a discrete transistor shunt voltage regulator is given below. These regulators provide a constant output voltage. A block diagram containing the parts of a typical power supply and the voltage at various points in the unit is shown in fig.
The block diagram of transistor series voltage regulator is shown in above figure. Block diagram of 3 terminal ic based voltage regulator fixed voltage regulators. Voltage regulator circuit to get constant dc output voltage. When the control element is in series with the load the output is given by vout vin vs.
An op amp circuit used as an error amplifier.
