[time-nuts] Parallel voltage regulators

[Kit Scally]

Tom C,

As Bruce notes below, the LM338K is a 5 amp job with a 35v max DC input
rating.
Just allow adequate heatsinking otherwise the 338 will "foldback" due to
over temperature.
There's plenty of on-line help to select the resistor values for 24
volts o/p.
If you're really keen (?), add a few diodes with the mandatory bypass
caps and you're cooking !

Cheers,

Kit

Hej Magnus

Since the output voltage range of a 7824 is 23 - 25V that arrangement
wont work very well unless you match all 7824's to within say 50mv or so
of the same output voltage and mount them on a common heat sink. If you
want to use a 3 terminal regulator why not just use an LM338 (plus a
couple of resistors to set the output voltage) or similar device?
