So I need to replace the following voltage regulator in an old Atari as it's registering 0.5V between output and ground and 24V on the input, but it's supposed to be providing 12V on the output side of things.
I'm trying to establish whether either of the following (locally available) parts are suitable replacements:
I'm a complete newbie to electronics (I'm a software guy) but I've read on here that the M is for Medium current, so I'm guessing that the 3A regulator I linked to would be capable of the job, but figured it'd be better to ask than to burn out some other component.
What do the parts of the component code mean? I guess the 12 in
UA85M12UC means 12V, but I have no idea about the
