Adjustable Output Regulator with Op-Amp

Adjustable Output Regulator

With adjustable voltage regulator the circuit voltage can be obtained varies from 7  to 20 VDC. This circuit requires a voltage input> = 20VDC

Circuit Notes
The addition of an op amp MC1741 allows adjustment to higher or intermediate values while retaining regulation characteristics. The minimum voltage obtainable with this arrangement is 2.0 volts higher than the regulator voltage.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
