1 / 13 page RN5RF SERIES LOW RIPPLE VOLTAGE REGULATOR WITH EXTERNAL TRANSISTOR NO. EA-043-111116 1 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 mA and several hundreds mA. 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. FEATURES • Supply Current .............................................................Typ. 30μA • Supply Current (Standby) ...........................................Typ. 0.1μA • Output Voltage Accuracy..............................................±2% • Ripple Rejection...........................................................Typ. 60dB (f=1kHz) • Dropout Voltage ...........................................................Typ. 0.1V (IOUT=100mA, dependent on External Tr.) • Temperature-Drift Coefficient of Output Voltage ..........Typ. ± 100ppm/°C • Line Regulation ............................................................Typ. 0.05%/V • Output Voltage Range..................................................1.2V to 6.0V (0.1V steps) (For other voltages, please refer to MARK INFORMATIONS.) • Package .......................................................................SOT-23-5 • Current Limit for external Tr. ........................................Current limit Typ. 8mA APPLICATIONS • Power source for battery-powered equipment • Power source for hand-held communication equipment, cameras, and VCRs • Power source for home appliances |
