If your input bus dips below that — say during a cranking event or battery sag — the output follows. ## 500 mA output with industrial temp coverage Rated for 500 mA continuous output, with a quiescent current of 2 mA. Protection circuits cover over-temperature, reverse polarity, and short circuit — three failure modes common in field wiring and hot-swap scenarios. ## Package and mounting — DDPAK/TO-263-3 Surface-mount DDPAK/TO-263-3 (3-lead plus tab). Tube shipment; no reel or tape for automated pick-and-place without a tube feeder or tray.","metaTitle":"Texas Instruments LM2937ES-3.3/NOPB LDO Regulator","metaDescription":"Texas Instruments LM2937ES-3.3/NOPB LDO voltage regulator, fixed 3.3V output, 500mA, 1V dropout at 50mA, -40°C to 125°C, DDPAK/TO-263-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"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)":"1.25 A","Voltage - Output (Max)":"-","Supplier Device Package":"DDPAK/TO-263-3","Current - Quiescent (Iq)":"2 mA","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa0d88b5b31623656f74345e6f33b73f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2937ES-3.3%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2937ES-3.3-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/LM2937ES-3.3-NOPB when reusing this data.
