STMICROELECTRONICS LF00 SERIES User Manual
The LFOO series are very low‑dropout (0.45 V) voltage regulators with ultra‑low quiescent current (50 µA OFF, 500 µA ON) and output currents up to 500 mA. They are offered in PENTAWATT, TO‑220, TO‑220FP, DPAK and PPAK packages and include a shutdown logic control pin for power‑saving applications.
The manual contains absolute maximum ratings, thermal data, connection diagrams, ordering codes, test circuits, detailed electrical characteristics for each voltage option, mechanical dimensions for tape‑and‑reel packaging, and safety/legal notices.
