15 Voltage Regulator Circuit Diagram. Voltage regulator, as name suggests, is a circuit which is used to regulate the voltage. A dc voltage regulator is a device which maintains the output voltage of an ordinary power supply constant irrespective of load variations or changes in input a.c.
This form is very common for voltage reference circuits. New current limiting circuitry allows transient load currents up to 24a to be supplied for 500ms without causing the regulator to current limit and drop out of regulation during the transient. 2n3055 wide range variable voltage regulator.
With this simple circuit however, regulation is not perfect, and variations in output do occur for the following reasons.
15 Voltage Regulator Circuit Diagram. Dc voltage regulator circuit diagram. A shunt voltage regulator works by providing a path from the supply voltage to ground through a variable resistance. Regulated voltage is smooth supply of voltage, free from any as you can see the circuit diagram for series voltage regulator, npn transistor t1 is the series element and a zener diode is used to provide the. Voltage regulator module (vrm) is an electronic circuit that regulates and down steps voltage from its input (e.g., system power rail) to its output (e.g., integrated circuits).
