Product Summary

The LM338K is designed as one kind of three-terminal 5-A adjustable voltage regulator device that is exceptionally easy to use and require only 2 resistors to set the output voltage. And this device is packaged in standard steel TO-3 transistor packages.

Parametrics

Absolute maximum ratings: (1)Power Dissipation: Internally LimitedW;(2)Input-Output Voltage DIfferential: 35V;(3)Operating Junction Temperature Range: 0℃ to 125℃;(4)Storage Temperature Range: -65℃ to 150℃;(5)Lead Temperature (Soldering, 10 seconds): 300℃.

Features

Features: (1)guaranteed 7A peak output current; (2)guaranteed 5A output current; (3)adjustable output down to 1.2V; (4)line regulation typically 0.005% / V; (5)load regulation typically 0.1%; (6)guaranteed thermal regulation current limit constant with temperature; (7)standard 3-lead transistor package.
