Hi y'all !
I'm having great success with a simple little +/-7 volts "slow power-up/down" circuit but realized the n & p-ch power MOSFETS I picked for experimenting (cheap and plentyful IRF531 & IRF9531) are a tad overkill (I only need about 100-150mA, max) and bulky...
I subbed a small BS170 for the IRF531 (at 500mA/1.2ohm Rds-on, gets the job done just fine; and since the whole thing is housed in a small 1590B Hammond box, the TO-92 package shoor' is appreciated !) So I'd be looking into a "common-place" p-channel equivalent; any ideas ?
See ya !
Joël
P.S.: could also be an altogether different n & p-channel pair... ? very low Rds-on... ? maybe a dual-matched package... ? IDK ! I'm really just waking up to the world of MOSFETs, so would greatly appreciate any suggestions. Thanks a lot !
