Variable Voltage Regulation


Posted on Oct 6, 2012

Controlling the output voltage from a regulator can be made variable in three ways:- 1. Using a fixed reference zener diode to increase the output by the value of the zener 2. A variable resistor for variable output, note that a voltage less than the nominal regulator is not possible 3. A chain of diode such as 1N4001, this increases the output by +0.7 V for every diode used.

This is simple, but offers and explains in very few words the way the circuit works and may modified, in practice, at a novice level. Kudos.
