Circuit Diagram Voltage Regulator. Working of transistor shunt voltage regulator if the input voltage increases the v b e and v o also gets increased. You can adjust the output voltage by varying the pot.
The lm317 ic helps in current limiting thermal overload protection and safe operating area protection. It is a series type of linear voltage regulator. This component does not have any configurations.
This power supply can provide current upto o5 ampere.
Actually when v i n increases the current i i n also increases. It is a series type of linear voltage regulator. The transistor t1 works as the actual regulator by switching a relatively high current with a maximum of 5 amperes. The circuit consists of an npn transistor and a zener diode along with a series resistor rseries that is connected in series with the input supply.
