Hi,
With this PS, trying to operate 2 relays(5v, spdt, rated coil current 80mA for each) with pic mcu.
It is noticed that at no load(when the relays not being operated) the zener(5.1v, 1.3watt) is geeing heat.
And if the relays are kept turned on the zener is ok.
Can you suggest what should i do.
The ckt of PS is attced here..
tnx
