LM337H/NOPB TI Linear Voltage Regulator | TO-3 | -1.2V to -37V, 1.5A

Product Overview

The LM337H/NOPB is a three-terminal adjustable negative voltage regulator from Texas Instruments, capable of supplying 1.5A over an output voltage range of -1.2V to -37V. Housed in a robust TO-3 metal can package, it offers excellent thermal performance and reliability for demanding applications. The device requires only two external resistors to set the output voltage, simplifying design. It features internal current limiting, thermal shutdown, and safe-area compensation, making it virtually immune to overload.
