Dear Friends,
The transformer of my power supply (which I used for 4-5 years) has given away recently. I want to build a new PS with some more options.My specifications are:
Current rating 1.5 A
Ripple less than 0.1%
5 Volts dual rail well regulated/balanced output
12 Volts dual rail well regulated/balanced output
Variable regulated output say from 1.25V to 24Volts (single rail) (I know I can use LM337,317 or 350)
Digital voltmeter/ammeter.
Ckt for blown fuse indicator.
I wanted to use IC regulators with minimum number of transistors. In my country it is difficult to obtain 2N...type transistors and multi secondary power transformers. (However, I have some 2N3055 pwr. Trs. in hand)
If you can help me to find a suitable ckt in internet or if you have any, please contact me through this page or you may directly e-mail to me on ravi@ualink.lk
Thanks & regards
Ravi
