On-chip protection covers over-temperature, reverse polarity on the input, and output short-circuit, which reduces the need for external clamp diodes or supervisory ICs. ## Package and footprint — DDPAK / TO-263-5 The device is supplied in the DDPAK/TO-263-5 surface-mount package (5 leads plus exposed tab), also referred to as TO-263-6, D²Pak.","metaTitle":"LM2931CS/NOPB – TI Adjustable LDO, 100 mA, DDPAK, Active","metaDescription":"Texas Instruments LM2931CS/NOPB positive adjustable LDO regulator, 100 mA output, 300 mV dropout max, PSRR 55 dB at 120 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","PSRR":"55dB (120Hz)","Series":"-","Package":"Bulk","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-263-6, D²Pak (5 Leads + Tab), TO-263BA","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LM2931","Protection Features":"Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~85°C","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"0.3V @ 100mA","Current - Supply (Max)":"15 mA","Voltage - Output (Max)":"24V","Supplier Device Package":"DDPAK/TO-263-5","Current - Quiescent (Iq)":"1 mA","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6600","priceTiers":[{"qty":1,"price":"$2.66000","currency":"USD"},{"qty":10,"price":"$2.39000","currency":"USD"},{"qty":25,"price":"$2.25520","currency":"USD"},{"qty":100,"price":"$1.92140","currency":"USD"},{"qty":250,"price":"$1.80412","currency":"USD"},{"qty":500,"price":"$1.57860","currency":"USD"},{"qty":1000,"price":"$1.30799","currency":"USD"},{"qty":2500,"price":"$1.27650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bc5f9d253d87c0f5bb975d3751d9071d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2931CS%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is the LM2931CS/NOPB obsolete or still active?","answer":"It is listed as active with no end-of-life notice from Texas Instruments."},{"question":"What package does the LM2931CS/NOPB come in?","answer":"It is supplied in a DDPAK/TO-263-5 surface-mount package (5 leads plus exposed tab), also described as TO-263-6, D²Pak."},{"question":"What does the /NOPB suffix mean on the LM2931CS/NOPB?","answer":"The /NOPB suffix indicates the device is lead-free (RoHS3 compliant) and does not contain lead in the plating or solder terminations."},{"question":"Is the LM2931CS/NOPB adjustable or fixed output?","answer":"It is an adjustable output regulator, with the output set by an external resistor divider."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2931CS-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/LM2931CS-NOPB when reusing this data.
