Product Summary

The LM317H is a 1.2V to 37V voltage regulator. It is a monolithic integrated circuit in TO-220, ISOWATT220, TO-3 and D2PAK packages intended for use as positive adjustable voltage regulators. The LM317H is designed to supply more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37V range. The nominal output voltage is selected by means of only a resistive divider, making the LM317H exceptionally easy to use and eliminating the stocking of many fixed regulators.

Parametrics

LM317H absolute maximum ratings: (1)Vi-o Input-output Differential Voltage: 40 V; (2)IO Output Current: Intenrally Limited; (3)Top Operating Junction Temperature for: 0 to 125 ℃; (4)Ptot Power Dissipation: Internally Limited; (5)Tstg Storage Temperature: -65 to 150 ℃.

Features

LM317H features: (1)output voltagerange: 1.2 to 37v; (2)output current in excess of 1.5a; (3)0.1% line and load regulation; (4)floatingoperation for high voltages; (5)complete seriesof protections: current limiting, thermal; shutdown andsoa control.
