The dropout voltage is specified at 1V max at 50 mA load — so the input rail needs at least 11V to regulate cleanly; at full load the dropout climbs, but the datasheet curve gives the headroom you need for the worst-case line transient. Built-in protection against over-temperature, reverse polarity, and output short circuits means you can skip the external crowbar or series diode in many designs — one less BOM line to manage. ## Industrial temp grade and package The TO-220-3 through-hole package makes it a straightforward retrofit on existing boards with a 0.100-inch pitch footprint, and the tab is the ground plane — bolt it to a heatsink if the load stays above 300 mA continuously. Quiescent current is 2 mA typical, and the maximum supply current is 20 mA — low enough that the regulator's own dissipation won't steal from the load budget in a lightly loaded system. ## Active production, no LTB watch needed The base product number LM2937 covers a family of fixed-voltage outputs, so if your next revision needs a different voltage, the pinout and footprint stay the same.","metaTitle":"LM2937ET-10/NOPB – Texas Instruments 10V Fixed Output LDO","metaDescription":"Active 10V fixed-output LDO from TI, 500 mA, 1V dropout at 50 mA, industrial temp -40°C to 125°C, TO-220-3.
