Hello,
I have made small power supply of 15V using 7815. A 230V to 18V transformer followed by a bridge rectifier and followed by a filter. The output of the filter is given to 7815. A capacitor is also used after 7815. The circuit is giving output of 15V when it is no load and lightly loaded(around 20 mA). But for little higher loads, the output voltage is dropping. The datasheet says that we can draw till 1.5A. But I am unable to draw even 100 mA at constant 15V. Why is this happening? What could be the issue.
Thanks,
