Hi, can the VB408 voltage regulator ( http://www.datasheetcatalog.org/datasheet/SGSThomsonMicroelectronics/mXttvuy.pdf ) be used as a constant current source as shown in the picture (provided Iout<40mA)?
I've never used this regulator, but with a coarse view of the data sheet I think this will be possible - within a range between 1.2mA and 40mA.
Thanks, that's exactly what I had been hoping for. Guess I'll give it a shot.
It passed the smoke test and appears to work. BTW: The VB408 is no longer in production, but I had a couple stashed away. The only other high voltage regulator I know of that is still in production is the LR8, but that one is limited to 20mA.
This is an action like pigs feed with pearls!
