The LM2937ES-8.0 is listed as obsolete. Current pricing and stock position are confirmed at quote time. ## Package and mounting — DDPAK/TO-263-3 Supplied in a TO-263-4 / D²Pak surface-mount package (3 leads plus tab), also referenced as DDPAK/TO-263-3.","metaTitle":"LM2937ES-8.0 LDO Regulator, 8V Fixed, 500mA, TO-263-3","metaDescription":"LM2937ES-8.0 positive fixed LDO regulator, 8V output, 500mA, -40°C to 125°C, TO-263-3 package.

The DDPAK/TO-263-3 package relies on the PCB copper area under the exposed tab for heat dissipation. At 500 mA with a 26 V input dropping to 8 V, the power dissipation is 9 W — a heatsink or forced airflow is required; at lighter loads the copper pour alone may suffice. The datasheet's thermal resistance curves should be consulted for the specific layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2937ES-8.0","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-8.0 when reusing this data.
