This means you can omit the usual Schottky diode on the input for reverse-battery protection and skip the PTC resettable fuse on the output — the regulator handles both internally. The quiescent current is 2 mA typical, rising to 20 mA max under full load, which is modest for a 500 mA LDO but worth noting if the rail is always-on in a battery-powered system. It is in current manufacture by Texas Instruments, so there is no imminent obsolescence risk for ongoing designs. ## Temperature range suits industrial and automotive environments The DDPAK package has an exposed metal tab on the bottom (the tab is the output pin) — a good thermal via pattern under the tab pulls heat into the board copper, keeping the junction temperature within limits at full 500 mA output.","metaTitle":"LM2937ESX-15/NOPB – 15V Fixed Output LDO, 500 mA, DDPAK-3","metaDescription":"Texas Instruments LM2937ESX-15/NOPB: 15V fixed-output LDO, 500 mA output, 1 V dropout at 50 mA, -40°C to 125°C range, DDPAK/TO-263-3 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":"Tape & Reel (TR); Cut Tape (CT)","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":"Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"1V @ 50mA","Current - Supply (Max)":"20 mA","Voltage - Output (Max)":"-","Supplier Device Package":"DDPAK/TO-263-3","Current - Quiescent (Iq)":"2 mA","Voltage - Output (Min/Fixed)":"15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5300","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":"$1.82880","currency":"USD"},{"qty":250,"price":"$1.71720","currency":"USD"},{"qty":500,"price":"$1.50256","currency":"USD"},{"qty":1000,"price":"$1.24497","currency":"USD"},{"qty":2500,"price":"$1.21500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa0d88b5b31623656f74345e6f33b73f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2937ESX-15%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2937ESX-15-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2937ESX-15-NOPB when reusing this data.
