im around somewhere crusher,
about the regulator with pass transistor biasing, there was a post on here some time ago suggesting that only one diode was needed and i dont understand diodes in thermal tracking,
take a tip from me, use two diodes, one in contact with the heatsink very close to the finals or on the cap of the finals and the other in contact with the pass transistor,
using one diode dont work, using two diodes but only having one sensing heat works but drifts positive as the pass transistor heats up,
using two pass transistors one as the pass element and the base emitter junction of an identical device to thermal track the pass transistor works much better than a single diode,
check it out for yourself, you will see who does and dont understand vdrop in diodes and biasing, the fluke dont care much about opinions
