R×5RE Series are voltage regulator ICs with high output voltage accuracy and ultra-low quiescent current by CMOS process.
The R·5RE series are CMOS voltage regulator ICs offering ultra‑low quiescent current, low dropout voltage, and high output‑current capability. Two package types are offered – TO‑92 and SOT‑89 – and the devices include built‑in current‑limit circuitry and stepwise output‑voltage setting.
The manual provides detailed absolute‑maximum ratings, electrical characteristics, pin configurations, and example circuits such as voltage‑boost and current‑boost topologies, helping designers implement stable low‑noise power supplies.
| Quiescent Current (typical) | 1.1 µA (R·5RE30A, VIN=5.0 V) |
|---|---|
| Dropout Voltage (typical) | 0.5 V (R·5RE50A, IOUT=60 mA) |
| Maximum Output Current (typical) | 120 mA (R·5RE50A) |
| Temperature‑drift Coefficient | ±100 ppm/°C |
| Line Regulation | 0.1 %/V |
The typical quiescent current is 1.1 µA when VIN is 5.0 V.
The R·5RE50A can deliver up to 120 mA of output current.
Output voltage is set stepwise in 0.1 V increments from 2.0 V to 6.0 V by selecting appropriate resistor values.
