The regulated power supply converts the standard 220 volts, 50 or 60 Hz AC available at wall outlets into a constants DC voltage. It is one of the most common electronics circuits that we can find. The DC voltage produce by a power supply is used to power all the types of electronic circuits, such that television receiver, stereo system, CD ...

A realistic DC power supply has a voltage that is not exactly constant and the current is limited by the circuit. The variation in voltage is called ripple. The power supplied by the power company is an ac voltage, which is a sinusoid of frequency 60 Hz and magnitude of 170 V = 120 Vrms.
REGULATED DC POWER SUPPLY
Linear regulated power supply . 1.3.1 AC/DC supply . Switched-mode power supply . Programmable power supply . Uninterruptible power supply . High-voltage power supply . Our project is a regulated DC power supply 12V-3A. The voltage produced by an unregulated power supply will vary depending on the load and on variations in the AC supply voltage.
