The 1.5A output current and 77dB PSRR at 120Hz make it suited for powering analog rails in industrial, telecom, and test equipment where a clean negative supply is needed. The TO-204AA (TO-3) steel package provides a hermetic seal and a large thermal mass for heat sinking through the chassis. No successor part is recorded in the lifecycle entry. For new designs, a current-production negative adjustable regulator with similar voltage and current ratings should be selected. ## 77dB PSRR and the steel TO-3 package The 77dB PSRR at 120Hz means the regulator attenuates full-wave-rectified ripple by a factor of about 7000 — relevant for linear supplies fed from a 50/60 Hz mains transformer. The 'STEEL' suffix indicates the can material — steel versus the more common nickel-plated copper — which affects thermal conductivity and corrosion resistance in humid environments. ## Protection features and output configuration The single-channel negative output is adjustable via two external resistors. Built-in protection includes over-current limiting, over-temperature shutdown, and short-circuit current limiting — these are standard for the LM337 family and prevent damage under output fault conditions.","metaTitle":"LM337HVK STEEL/NOPB Negative Adjustable Regulator, -50V","metaDescription":"Texas Instruments LM337HVK STEEL/NOPB negative adjustable linear regulator, -50V input, 1.5A output, 77dB PSRR at 120Hz, TO-204AA steel package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","PSRR":"77dB (120Hz)","Series":"-","Package":"Bulk","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"TO-204AA, TO-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"1.5A","Base Product Number":"LM337","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Negative","Operating Temperature":"0°C~125°C","Voltage - Input (Max)":"-50V","Voltage Dropout (Max)":"-","Voltage - Output (Max)":"-47V","Supplier Device Package":"TO-3-2","Voltage - Output (Min/Fixed)":"-1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3970b6ef653bc89b15c3a6a19f45ff18.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM337HVK%20STEEL%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM337HVK-STEEL-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/LM337HVK-STEEL-NOPB when reusing this data.
