Minimum input voltage for linear voltage regulator
Posted: 14 Jan 2019, 18:38
What is the minimum input voltage for a 78l08 to work properly? I understood that at least 1.7 volts was needed on top, so really around 10 volts. I have just built the Ibanez RC99 rotary using Dirk Hendrik's build guide available via this forum. The pedal expects 9 volts. The schematic shows some power filtering before and after the 78l08 as usual. I measured 7.6 volts after the regulator which would be within the range given by the datasheet, but the datasheet gives a 2 volt dropout voltage.
Confused? I certainly am.
