The LD1585C is a low dropout voltage regulator capable of providing up to 5A of output current. The device features a low dropout voltage and very fast transient response. It is suitable for low voltage applications where transient response and minimum input voltage are critical.
The LD1585Cxx is a 5 A low‑dropout, fast‑response positive voltage regulator designed for low‑voltage applications where transient response and minimal input voltage are critical. It offers typical dropout of 1.2 V, up to 1.4 V at full load, and an output tolerance of +1 % at 25 °C.
The document includes a diagram, pin configuration, absolute maximum ratings, typical application circuits, detailed electrical characteristics, package mechanical data, and revision history. It lists available packages (TO‑220, DPAK/A) and provides order codes for fixed‑output versions ranging from 1.5 V to 9 V.
