Basic Positive High Voltage Regulator:
The Basic Positive High Voltage Regulator is given by
For this type, output voltage varies from +7V to +37 V and IL ≤ 150 mA.
The non-inverting terminal connected to Vref through R3 . Due to this arrangement the error amplifier acts as non-inverting amplifier.
The gain is
The output voltage is,
This is also called basic high voltage low current regulator.
