Hi!
Attached is a schematic of a linear psu I draw. +/- 17v, made with lm317/337 regulators. Those rails are quite normal.
My doubt arise about the other two positive rails after the 10R/1000uf rc filter.
1.) ¿Is it ok to share this RC filter for two 78xx regulators? (7824 and 7812).
1.1) I expect to draw not much current from each 78xx regulator..(+100ma max), so i could have draw
78L24/78L12 in the schematic... :
2.) ¿Or is it better to give each regulator its own input capacitor?.(smaller value).
3.) In any case i derived those additional rails from the same diode bridge.
Thank you for your help!
