|The fixed voltage power supply is useful in applications where an adjustable output is not required. This supply is simple, but very flexable as the voltage it outputs is dependant only on the regulator and transformer you choose. The maximum output current is 1.5A.|

|shouldn't the T1 be at least 2V more than the required voltage?|
|how to generate a one volt power supply from an main ac supply.|
|I am involved in a senior project that requires me to build a 6V 1.5A power supply. How can I determine what the values I need for the Fixed Voltage Power Supply schematic that is provided from your website? Your help is very much needed. Thanks.|
|The 1/2/3 are the pins on the LM78xx. I have a question though. Since I'm going for 5v out, I imagine that I could replace the LM78xx with the R-785.0-1.0 from RECOM? Better efficiency but would only have 1A out, for me that's fine as it's only to power USB type devices.|
|can u please tell me why 3 & 2 is written in U1|
|its very easy ,use ( LM7805 ) to get 5v DC power supply|
|Should the Switch (S1) not be on the Positive / Live side before the transformer?|
|what is the purpose of D1, D2, C2, C3, and C4? And, why you didn't include resistor in the filter and for the load? thanks... hope you answer my questions ASAP...thanks again|
|Hi, I would like to build a power supply that can give out 24V DC at 5A from 240V AC. What parts in this circuit do I need to change to achieve this. Thanks.|
|ASSALAM o ALAIKUM! sir i want the circuit which regulate from 1.2 to 30 but i want that circuit having transformer whose AC input is 220 volt i have seen your circuits in your circuits AC input in the transformer is 120. plz give me the circuit as soon as possible i shall be very thank ful to u for this act of kindness|
