Its maximum dropout voltage of 1V at full load means the input must stay above 11V to maintain regulation — critical for headroom in 12V or 15V intermediate rails. The protection set — over-temperature, short-circuit, transient voltage, and mirror-image insertion — reduces the need for external clamp diodes or crowbar circuits on the output. ## Dropout headroom and quiescent current trade-off With a 10mA quiescent current and 20mA supply maximum, the LM2937ES-10/NOPB draws a fixed overhead regardless of load — acceptable for always-on rails but less efficient than a low-Iq LDO for battery-powered designs. The fixed 10V output eliminates external resistor dividers, saving two components and a feedback-node noise path. Compared to the adjustable LM1085IS-ADJ/NOPB, this part offers a simpler BOM for a fixed 10V rail, though the LM1085 can deliver 3A for higher-current needs. ## Active production — no obsolescence signal Texas Instruments continues to manufacture this part, and it is ROHS3 compliant. Sourced to order against BOM quantities; confirm the tube quantity for your line — typical tube count for TO-263 is 45 or 50 pieces per tube, but verify with the order desk. ## TO-263-4 (D2PAK) footprint and thermal pad Surface-mount assembly with standard reflow profile; the tab solder joint is critical for both electrical connection and thermal dissipation.","metaTitle":"LM2937ES-10/NOPB 10V Fixed LDO Regulator 500mA TO-263","metaDescription":"Texas Instruments LM2937ES-10/NOPB: 10V fixed output LDO, 500mA, 1V max dropout at full load, -40°C to 125°C junction range, TO-263-4 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"-","Series":"-","Package":"Tube","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-263-4, D2PAK (3 Leads + Tab), TO-263AA","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"500mA","Base Product Number":"LM2937","Protection Features":"Mirror-Image Insertion, Over Temperature, Short Circuit, Transient Voltage","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"1V @ 500mA","Current - Supply (Max)":"20 mA","Voltage - Output (Max)":"-","Supplier Device Package":"TO-263 (DDPAK-3)","Current - Quiescent (Iq)":"10 mA","Voltage - Output (Min/Fixed)":"10V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4100","priceTiers":[{"qty":1,"price":"$2.53000","currency":"USD"},{"qty":10,"price":"$2.27500","currency":"USD"},{"qty":25,"price":"$2.14640","currency":"USD"},{"qty":100,"price":"$1.82890","currency":"USD"},{"qty":250,"price":"$1.71724","currency":"USD"},{"qty":500,"price":"$1.50258","currency":"USD"},{"qty":1000,"price":"$1.24500","currency":"USD"},{"qty":2500,"price":"$1.21503","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa0d88b5b31623656f74345e6f33b73f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2937ES-10%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What are equivalent or replacement parts for LM2937ES-10/NOPB?","answer":"For a fixed 10V rail, this part is the direct choice.
