#97395 - get 4.91V now !! Responding to: ???'s previous message |
Hello
Thanks for the quick replies. I had a small diode connected at the output of 78l05. It`s a small 1n4148 which should protect circuit. It`s not drawed in the schematic cause it was a "last minute idea". With the diode I get 4.7V. Without.. 4.91V. I will have to remove it from the circuit. It`s 4.91V enough to program the at89c2051?
