Description

The RQ5RW29BA is a voltage regulator IC from the Rx5RW Series. It is a CMOS-based IC that provides accurate output voltage with ultra-low supply current. The IC consists of a driver transistor, a voltage reference unit, an error amplifier, resistors for setting output voltage, and a current limit circuit. The high accuracy of the output voltage is fixed, and the ICs are protected from destruction even if the output voltage is shorted to ground. Additionally, RQ5RW29BA has a chip enable function that allows minimization of the supply current on standby, and it is possible to mount the ICs on boards with high density due to their small packages.
