Built-in protection includes over-current, over-temperature, and short-circuit limiting, so it can survive a momentary output short without external crowbar circuitry. ## Output range and input limits — what fits your rail Output is adjustable from 1.25 V to 37 V, matching the maximum input voltage rating of 37 V. Quiescent current is 10 mA typical — this flows to ground and does not pass through the load, but it does add to the total input current budget. ## PSRR and noise — where the 64 dB at 120 Hz matters Power-supply rejection ratio is 64 dB at 120 Hz. ## Temperature grade and package — board-fit check The TO-220-3 package (through-hole) requires a heatsink for loads above about 0.5 A at elevated ambient — the tab is ground and can be bolted to a chassis or clip-on heatsink.","metaTitle":"Texas Instruments LM317T/NOPB Adjustable Regulator, 1.5A","metaDescription":"Texas Instruments LM317T/NOPB adjustable positive voltage regulator, 1.5A output, 1.25V to 37V range, PSRR 64dB at 120Hz.
