Regulated Power Supply –
Working, Circuit Diagram
and Applications
Introduction
A regulated power supply is an electronic circuit that
provides a stable and controlled output voltage, current,
or power. It is used to power electronic devices and
circuits that require a specific level of voltage or current
to operate correctly. The regulated power supply ensures
that the output voltage or current remains constant,
regardless of changes in the input voltage or load current.
