Product Summary
The LM338K is an adjustable 3-terminal positive voltage regulator capable of supplying in excess of 5 A over a 1.2 V to 32 V output range. The LM338K is exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation comparable to many commercial power supplies. The LM338K is supplied in a standard 3-lead transistor package.
