Power Supply Regulators Unit 1 – Circuit Board Familiarization
UNIT 1 – CIRCUIT BOARD FAMILIARIZATION
UNIT OBJECTIVE
At the completion of this unit, you will be able to identify the circuit blocks and major
components on the POWER SUPPLY REGULATION CIRCUITS circuit board.
UNIT FUNDAMENTALS
Most electronic devices require power supply regulation circuits.
A power supply regulation circuit provides a constant voltage or current to a system when
changes in the line voltage or load resistance occur.
NEW TERMS AND WORDS
integrated circuit (IC) - any electronic device in which active and passive elements are
contained in a single package.
discrete - an individual circuit component, complete in itself, such as a resistor, diode, capacitor,
or transistor, used as an individual and separable circuit element.
EQUIPMENT REQUIRED
F.A.C.E.T. base unit
