If your voltage drops, it's because the load is drawing too much current (or another way to look at it is that the supply isn't able to supply enough current). Current and Voltage NEVER operate independently of one another, it is a reciprocal relationship, because voltage is not an indicator of what's there, it is an indicator of what has been CONSUMED in moving current through the 'gap' (anything between the poles of any power-supply is a 'gap' a form of resistance or impedance (or both)).Actually i have tried by connecting simple dc bulb to it... The 7.21 volts that is on output it drops to zero after loading. So i thought there must be something wrong with the feedback so i replaced tl431 after that alteration this ticking thing happened.
So what's preventing it from supply enough current?
