79L05?
hELLO kt315
12V connection and regulator may be good idea, but I think is a mistake to use 10k instead of 4.7k in R5, R6 because power-up is much slower, also, under heavy load - may not reach high peak voltage.
Use Fairchild KA79L08 (or equivalent) regulator instead of 79L05. Also, schottky diodes are more efficient than 1N4148.
KA79L05 can use 6ma by itself, so a low power LDO would be better. Know of any -8V LDO?
Can use 1N5817 to get -7V with 8V connection, but no regulation.
