Voltage Regulator
Hi,
I am new here and a bit new to electronics too.
I am creating a variable light source to be controlled through a D/A card ( On a PC) which has a output of 0-10V ( 8 bits ) from adlink technologies . I have interfaced this card with my application and have managed to vary the voltage at the output port through the application.
My problem is now to use this output to vary a regulated DC supply from 0-24V @ 30mA (max) using a standard LM 317 voltage regulator package.
Any help on this with a circuit diagram or link to information will be greatly appriciated.
I am attaching the National semiconductors application hints too for LM 317.
ciao,
