RN5RF SERIES
LOW RIPPLE VOLTAGE REGULATOR WITH EXTERNAL TRANSISTOR
NO. EA-043-111116
OUTLINE The RN5RF Series are CMOS-based voltage regulator ICs which control external driver transistors with high ripple rejection, high accuracy output voltage, low supply current. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, output voltage setting resistor, short circuit current limiting circuit and chip enable circuit. These ICs are suitable for constructing regulators with ultra low dropout voltage and an output current in the range of several tens of m A and several hundreds m A. In addition to low supply current by CMOS process, chip enable function can be used to conserve battery life during standby. Furthermore, a supreme ripple rejection and a transient response are suitable for portable communicator such as cell phones, PDAs, walky talkies. SOT23-5 (Mini Mold) package is available.
