add ko lang sa tanong ni oransomil, di natin kasi napagusapan dito ang cost... how much ba budget mong gustong i-shell out.. kasi if you want a simple and budget mo less than 50 petot para maging regulated and unregulated mong circuit.. puwede na ang lm 317.. actually puwede and an 317.. tignan mo sa mga datasheets.. hanap ka through google... ang pagkakaiba ng letters ay sa manufacturer.. make sure to check datasheets... reliable to buy sa alexan (sorry to plug the store) or kay deeco.

kung gusto mo naman ng transistor pass, puwede din.. ang basics ng regulator ng transistor pass as regular ay dapat may reference volatage ka, meaning gamit ka ng zener diode.. so kung example 12 v unregulated gusto mong gamitin ang transistor to regulate 9 volts.. gamit ka ng 9.1 zener diode at transistor.  Nung una nung wala pa ang mga lm78xx at lm317t, transistor ang ginagamit namin.. mga 18 years ago yun (napaghahalata ang edad ko:)).

patulong naman po. Need ko po schematic ng regulated power supply. want to regulate a +/-40V, 6AMP power supply. Meron akong nakikitang regulator pero single power supply po. Ang kailangan po kasi is regulator for split 40-0-40, 6A power supply (rectified and filtered na ito).

Salamat po.

Try reading Electronic Devices and Circuits Theory by Nashelsky and Boylstad. May topic na po dun about sa power supplies and regulators.

UPS? yes meron pong gumagamit ng ganun especially yung sinusoidal ang output.

Gaya nang power supply ng computer.
