The 60 dB PSRR at 120 Hz provides meaningful ripple rejection for sensitive analog loads on the negative supply rail. Housed in a TO-205AD / TO-39-3 metal can (TO-3 footprint), this through-hole package offers a hermetic seal and robust thermal performance, suited for high-reliability and harsh-environment deployments. ## Military temperature grade and protection features Built-in over-temperature and short-circuit protection reduce the need for external supervisory circuitry and improve fault tolerance on the board. ## Active production — sourcing through authorized channels . The base product number LM337 covers a family of negative adjustable regulators; the H suffix denotes the TO-3 metal can variant, and /NOPB indicates lead-free / RoHS-compliant finish.","metaTitle":"LM337H/NOPB Texas Instruments Negative Adjustable Regulator","metaDescription":"LM337H/NOPB negative adjustable voltage regulator from Texas Instruments. 500 mA output, 60 dB PSRR at 120 Hz, -55°C to 150°C range, TO-3 metal can.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"60dB (120Hz)","Series":"-","Package":"Bulk","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"TO-205AD, TO-39-3 Metal Can","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"500mA","Base Product Number":"LM337","Protection Features":"Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Negative","Operating Temperature":"-55°C~150°C","Voltage - Input (Max)":"-40V","Voltage Dropout (Max)":"-","Voltage - Output (Max)":"-37V","Supplier Device Package":"TO-3","Voltage - Output (Min/Fixed)":"-1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.4100","priceTiers":[{"qty":1,"price":"$20.41000","currency":"USD"},{"qty":10,"price":"$18.75400","currency":"USD"},{"qty":25,"price":"$17.97640","currency":"USD"},{"qty":100,"price":"$15.83870","currency":"USD"},{"qty":250,"price":"$15.06140","currency":"USD"},{"qty":500,"price":"$14.08968","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0778c63670ae2b9da77d4109fe26090b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM337H%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the PSRR of the LM337H/NOPB and why does it matter?","answer":"The LM337H/NOPB provides 60 dB of ripple rejection at 120 Hz. This is the typical power-supply ripple frequency from a full-wave rectifier; 60 dB attenuation means the output ripple is reduced by a factor of 1000, which is important for noise-sensitive analog loads such as op-amp rails or audio preamplifiers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM337H-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/LM337H-NOPB when reusing this data.
