National Semiconductor LM5008 Guide
The LM5008 is a high‑voltage (100 V) step‑down switching regulator that uses a hysteretic control scheme with an on‑time inversely proportional to the input voltage. It is offered in MSOP‑8 and thermally enhanced LLP‑8 packages and includes features such as intelligent current‑limit protection, thermal shutdown, and under‑voltage lockout.
The document contains detailed pin descriptions, electrical characteristics, typical performance curves, and recommended application circuits. It also lists absolute maximum ratings, package dimensions, and compliance information for life‑support and banned‑substance regulations.
