Product Summary

The RN5RG33AA is a voltage regulator IC with an external power transistor with high output voltage accuracy and lowest supply current by CMOS process. The RN5RG33AA consists of a voltage reference unit, an error amplifier and resistors. The device is suitable for constructing regulators with ultra-low dropout voltage and an output current in the range of several tens mA to several hundreds mA. Furthermore,the RN5RG33AA has a chip enable function, so that the supply current on standby can be minimized. Since the package for the device is SOT-23-5 (Mini-mold) package, high density mounting of the IC on boards is possible.
