Im havin a spot of trouble with fixed reg's on a diy power supply.
The power supply is a split rail affair, being 30-0-30v before regs.
Im getting 21.7 v out of the neg reg , it being a lm7915cv and being capable of 1.5amps, only using around 600ma.
Iv'e even used the suggested circuit on natsems web site..and it's still not dropping to 15v Any idea's
