LM338 (5A, 40V, low-IQ, adjustable linear voltage regulator)
BD 2.500
The LM138/LM238/LM338 are adjustable 3-terminal positive voltage regulators 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.
The careful circuit design has resulted in outstanding load and line regulation comparable to many commercial power supplies.
The LM338 or LM138 family is supplied in a standard 3-lead transistor package.
