LM309H/NOPB TI Voltage Regulator | TO-3 | 5V Output, 1.5A Current

Product Overview

The LM309H/NOPB is a monolithic integrated circuit voltage regulator from Texas Instruments (TI), designed to provide a fixed 5V output with a load current capability of up to 1.5A. Housed in a robust TO-3 metal package, it offers excellent thermal performance and reliability for demanding applications. The device requires only two external capacitors for operation, simplifying design and reducing component count. With built-in current limiting and thermal overload protection, the LM309H/NOPB ensures safe operation under fault conditions.
