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.
