It delivers up to 1.5A and includes over-temperature and short-circuit protection. Typical applications include providing the negative rail in dual-supply op-amp circuits, analog front-ends, or legacy -5V logic buses where a clean, regulated negative voltage is required. The TO-220FP (full-pack, isolated tab) simplifies heatsinking — no insulating washer needed between the tab and the heatsink. Through-hole mounting suits point-to-point wiring or PCB layouts with a common negative rail plane.

The L7905CP's full-pack (isolated) tab is the main difference — if your design relies on the isolated tab, stick with the CP suffix. For a direct cross, check the L7905CP datasheet for pin-compatible second sources from other manufacturers; no official ST alternate is published."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/L7905CP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/L7905CP when reusing this data.
