In Reply to: LM350 regulated DC PSU & HUM problem posted by Ewing on August 19, 2003 at 18:32:47:
The LM350 will shut down if it gets too hot, and it sounds like that's what is occurring. You need more heat sinking capability, how much depends on the dissipation of the regulator. What is the voltage into the regulator? If it's more than about 9 volts you will be dissipating a lot of heat (1.2 amps x 4 volts across the LM350 = almost 5 watts of heat.You'd be amazed how large a heat sink you need to keep the regulators cool enough.
