General Description
The LM138 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 5A over a 1.2V to 32V output range. They are 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 LM138 family is supplied in a standard 3-lead transistor package.

Features
■ Guaranteed 7A peak output current
■ Guaranteed 5A output current
■ Adjustable output down to 1.2V
■ Guaranteed thermal regulation
■ Current limit constant with temperature
■ P+ Product Enhancement tested
■ Output is short-circuit protected

Applications
■ Adjustable power supplies
■ Constant current regulators
■ Battery chargers
