概要
Description
LT3070MPUFD#PBF is Linear Technology’s Pb-free version of the LT3070, a versatile adjustable high‑voltage, current‑limit linear regulator. It integrates a control circuit and pass element to provide an adjustable output with current limiting, overcurrent protection, and thermal shutdown. Features often include remote sensing, soft-start, and a wide operating range suitable for high‑voltage power supplies and current‑source apps. The #PBF suffix denotes Pb‑free, RoHS‑compliant packaging; MPUFD indicates the small-outline package variant (e.g., MSOP/DFN style). Use it when you need a compact, adjustable regulator that can also limit current in high‑voltage applications, with protection features. For exact pinout, external components, input/output ranges, and thermal considerations, consult the datasheet.
