Product Summary

The LM317D2T is a adjustable voltage regulator. The LM317D2T is designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range. The nominal output voltage is selected by means of only a resistive divider, making theLM317D2T exceptionally easy to use and eliminating the stocking of many fixed regulators.

Parametrics

LM317D2T absolute maximum ratings: (1) Input-reference differential voltage VI-VO: 40V; (2) Output Voltage IO: Internally limited; (3) Input-reference differential voltage TOP: 0 to 125°C; (4) Power dissipation PD: Internally limited; (5) Storage temperature TSTG: -65°C to +150°C.

Features

LM317D2T features: (1) Output voltage range: 1.2 to 37V; (2) Output current in excess of 1.5A; (3) 0.1% Line and load regulation; (4) Floating operation for high voltages; (5) Complete series of protections: current limiting, thermal shutdown and SOA control.
