Overview

LM138/LM338 5-Amp Adjustable Regulators May 1998 LM138/LM338 5-Amp Adjustable Regulators 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.
A unique feature of the LM138 family is time-dependent current limiting.
The current limit circuitry allows peak currents of up to 12A to be drawn from the regul...
