It switches between 150 kHz and 500 kHz, with no synchronous rectifier — the external Schottky diode carries the catch current, which simplifies the layout but adds a diode drop to the efficiency curve. The adjustable output is set via external resistors from a 1.236 V reference up to 35 V. ## Rework and thermal-pad layout Without that thermal connection, the junction-to-ambient resistance climbs and the 3 A output derates early. The pin pitch is 0.65 mm, which is hand-solderable with a fine tip and flux, but the exposed pad needs a hot-air station or reflow profile. Pad 1 is marked by a chamfer on the package body — the orientation is unambiguous under magnification. It is ROHS3 compliant and carries the Automotive, AEC-Q100 series designation, meaning it meets the stress and reliability qualification for automotive-grade ICs.","metaTitle":"TI LM26003QMH/NOPB Buck Regulator, 3A, 20-HTSSOP","metaDescription":"Texas Instruments LM26003QMH/NOPB step-down buck regulator, 3 A output, 3-38 V input, adjustable, 150-500 kHz, -40 to 125°C, AEC-Q100, active, ROHS3.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"150kHz ~ 500kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"38V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"35V","Supplier Device Package":"20-HTSSOP","Voltage - Output (Min/Fixed)":"1.236V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8","priceTiers":[{"qty":1,"price":"$5.80000","currency":"USD"},{"qty":10,"price":"$5.20700","currency":"USD"},{"qty":25,"price":"$4.92280","currency":"USD"},{"qty":100,"price":"$4.26630","currency":"USD"},{"qty":250,"price":"$4.04752","currency":"USD"},{"qty":500,"price":"$3.63182","currency":"USD"},{"qty":1000,"price":"$3.09600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e0c2cc4862627492efeb776b95b0fd5e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM26003QMH%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM26003QMH-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/LM26003QMH-NOPB when reusing this data.
