Hi,

Acetronics is right in recommending 22ohms and i saw other designs (IK3OIL's frequency counter using LCD display) indicating backlit LCDs draw 60 mA and recommend 7805 but NOT 78L05. No heatsink is noticed.

Hi DynamoBen,

did you use 12V ,7805 and 11ohm resistor for Backlit? Still find No heat?
