Hi,
Am a total newbie. Trying to use a voltage regulator, LM338 to reduce voltage on a power supply from 35-37 down to 24v. I need a regulator that can handle 5A at those voltages.
I went to an online calculator on the 317 regulator and got the following figures for the standard, basic regulator circuit:
Input 35 v
Output 24 v
R3 120 ohm
R4 2.2K ohm
Vout 24.17
Questions - do these apply to the LM338 and are they correct?
Do I need a heat sink for this application with a TO-3 package of the 338?
Should I incorporate diodes in the basic circuit for protection?
Do I need capacitors and if so, what value?
What wattage resistors should I use?
TIA
