RP102Z281D5-TR-F

RP102x SERIES LOW NOISE 300mA LDO REGULATOR NO.EA-141-111020 OUTLINE The RP102x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit and a chip enable circuit. These ICs perform with low dropout voltage and "chip enable" function. The line transient response and load transient response of the RP102x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment. The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are SOT-23-5, DFN(PLP)1820-6, and WLCSP-4-P2, therefore high density mounting of the ICs on boards is possible.

ABSOLUTE MAXIMUM RATINGS Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the life time and safety for both device and system using the device in the field. The functional operation at or over these absolute maximum ratings is not assured. RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 4 RP102x ELECTRICAL CHARACTERISTICS • RP102xxx1B/D VIN=Set VOUT+1V for VOUT options grater than 1.5V.

For this purpose, use a capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance). (Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for phase compensation, the operation might be unstable. Because of this, test these ICs with as same external components as ones to be used on the PCB.) PCB Layout Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor C1 with a capacitance value as much as 1.0μF or more between VDD and GND pin, and as close as possible to the pins. Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring as short as possible. 6 RP102x TEST CIRCUITS VDD VOUT RP102x Series C1 CE C2 V VOUT IOUT GND C1=Ceramic 1.0μF C2=Ceramic 1.0μF Basic Test Circuit VDD A RP102x Series C1 ISS VOUT CE C2 GND C1=Ceramic 1.0μF C2=Ceramic 1.0μF Test Circuit for Supply Current Pulse Generator VDD VOUT RP102x Series P.G.
