The regulator can be changed for 12 volt and also for 15 volt, which is maximum for the specified transformer. Sir, can I use 9 volt transformer.

That thing looks very nasty and slimy too.

Hi Caloy it is not possible Hi Larry you have to use 6 1N diodes in series in forward biased condition between regulator common and negative bus to achieve 9volts from 5 volt regulator.

AN datasheet and specification datasheet Download datasheet. I needed the power supply right away, and there is no local source for the I have also made power supplies using this method, virtually identical to your schematic, with one difference. Leave a Reply Cancel reply Your email address will not be published. Can the regulator be changed into a 12v regulator without any other change in the circuit?

I used a heating, so after working for about 3minutes d regulator got bunt. Please go though notes it clearly indicates above mA you require proper heat sink.

One is connected in series with pin 2 and the negative supply be sure to remove the connection from pin 2 to the negative dataeheet which is shown in the schematicwhile the other is connected from pin 3 to pin 2.

Are you sure about diodes in rectifier.

Hope this is of use to someone.

Also, it is a good idea to heat sink the datasheet, as it will heat up quickly if more than a few mA is drawn an78099 the supply. Larry I apologize if there are any errors; if I can help, contact me at lspeed1 at comcast dot net. A 4 volt zener diode would work here also, in place of the rectifier diodes, but they are not often stocked by experimenters! Page 10 Request for your special attention and precautions in using the technical information and 1 If any of the products or technical information datashest in this book exported or provided to non-residents, the laws and regulations of the Have you used a good heat sink.

The capacitor value is not critical; I over-killed it with a 10uF electrolytic and a dafasheet. Stabilized fixed output voltage is obtained from. If you make the first resistor variable, you can make the power supply variable from 5 volts to about 12 volts or so, depending on the transformer and rectifier voltages and current rating.

This can also be accomplished by using a voltage divider with two resistors.

Thats a gud 1. C1 and C2 has blown because you might have used 16 or 25 volt capacitors use 50 volt rated capacitors only.

I also connected a 3K resistor from pin 3 of the to pin 2, to provide bias current for the series diodes, but the resistor value is not critical, as long as a few mA of current flows through the diodes independent of current from pin 2 of the Minimum should be greater than Hi Harish you can use. Sir i whant make a street light circuit project for my polytechnic diplom i am electrical engineering student so plz give me some idia sir i m wating for your answer….
