EUP7963 is a 3A low-dropout linear regulator that provides a low voltage, high current output with a minimum of external components.
The EUP7963 is a 3 A low‑dropout linear regulator that operates from 2.5 V to 5.5 V input and provides fixed output voltages of 1.5 V, 1.8 V, 2.5 V, 3.3 V or an adjustable range of 0.8 V‑4.5 V. It features ultra‑low dropout (750 mV at 3 A), high precision (+/-1.8% accuracy), low ground pin current (1 mA) and a quiescent current of 0.1 nA in shutdown mode, with thermal and current‑limit protection.
The document includes a block diagram, pin configuration for TO‑220‑3, TO‑220‑5, TO‑263‑3 and TO‑263‑5 packages, ordering information, absolute maximum ratings, electrical characteristics, typical operating curves, and application notes on external capacitor selection, on/off control, error‑flag operation, and adjustable‑output configuration.
