check in pcb version
I need both 3.3V and 5V in my circuit. hence, im using regulator lm1117 and lm7805.
i soldered the voltage regulator with the dc jack and capacitors, then i checked the voltage output from both voltage regulator.
lm1117 is working fine (has output of 3.3V) but lm7805 is getting HOT at the instant i plug to the dc jack.
is there something wrong with my PCB drawing?
i have checked the drawing. and found a mistake on the grounding. but when i add solder according to the brown line in the circle, same problem exist.
is there any other mistake i made with the lm7805 routing?
