The XC6405 Series are precise, low‑noise, high‑speed, high‑current low‑dropout regulators with built‑in voltage detector. They are fabricated using Torex’s CMOS process and are compatible with low‑ESR ceramic capacitors for added output stability.
Key features include selectable output voltage (0.9 V‑5.1 V) and detect voltage (0.9 V‑5.5 V) in 100 mV steps, maximum output current over 500 mA, low dropout voltage, high ripple rejection, and multiple package options (SOT‑25 and SOT‑89‑5). The datasheet provides detailed pin configurations, electrical characteristics, and typical application circuits for devices such as CD‑ROM, DVD, and portable AV equipment.
