LM138K

三端5的可调稳压器 THREE-TERMINAL 5 A ADJUSTABLE VOLTAGE REGULATORS

DESCRIPTION

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. 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.
