I am using a 555 IC as an oscillator at 40 KHz.
The circuit is working ok with my adjustable regulator power supply which I bought (100$).
Today I decided to use a transformer instead of my power supply for my oscillator.
I used a 7815 regulator chip and a KBP02 bridge rectifier (yes I connected a 1000uF & a 100nF capacitor across the rectifier outputs) but the output is not a catharsis output!
I have connected a 1000uf and a 100nF capacitor across the outputs of the 7815 chip too but there is not a pure output yet!.
Don't know what to do?
I want to get as stability as I can but don't know what to do?
The transformer is a 18 V,500mA
Any suggestion would be very appreciated
