The R5322N Series are voltage regulator ICs with high output voltage accuracy, low supply current, low dropout, and high ripple rejection by CMOS process.
The R5322N series are 2‑channel low‑dropout (LDO) voltage regulators designed for high output voltage accuracy, ultra‑low supply current, and excellent ripple rejection. They are suited for power supplies in handheld communication equipment, cameras, VCRs, camcorders, and other battery‑powered devices.
The manual details the series' features, selection guide, pin configuration, absolute maximum ratings, electrical characteristics, typical application circuits, and technical notes on component selection and layout. It also includes block diagrams, test circuits, and guidelines for ensuring stable operation.
