It is a positive-output, single-regulator device in a TO-263-4 (D²Pak) surface-mount package. The dropout is 1 V max at 50 mA. ## Protection set — built for field survival Over-temperature, reverse polarity, and short-circuit protection are all on-die. That means a swapped load or a miswired supply on a field retrofit won't instantly kill the regulator — the reverse polarity clamp takes the hit before the die sees reverse bias. The quiescent current is 2 mA typical, and the maximum supply current is 20 mA. For a 500 mA output, the 2 mA Iq is modest — it won't waste the thermal budget in a sealed enclosure. No stock-holding claim; each quote confirms current pricing and delivery.","metaTitle":"LM2937ESX-10/NOPB 10V Fixed LDO, 500mA, TO-263, Obsolete","metaDescription":"Texas Instruments LM2937ESX-10/NOPB fixed 10V output LDO rated 500mA in TO-263-4 (D²Pak).
