1 RP9x SERIES LOW NOISE 5mA LDO REGULATOR OUTLINE NO.EA-- The RP9x 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 a chip enable function which prolong the battery life. The line transient response and load transient response of the RP9x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment. RP9x Series contributes to the downsizing of the hand-held equipment because it can use the.μf ceramic capacitor. In addition to SOT--5, SC-88A and DFN- packages, a.8mm square ultra compact DFN(PLP)88- package is also available.

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.

6 RP9x TYPICAL APPLICATION VDD VOUT VOUT C RP9x Series C CE GND (External Components) C.μF MURATA: GRM55BCKA87B TECHNICAL NOTES When using these ICs, consider the following points: Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a capacitor C with.μf or more and good 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 C with a capacitance value as much as.μf or more between VDD and GND pin, and as close as possible to the pins. Set external components, especially the output capacitor C, as close as possible to the ICs, and make wiring as short as possible. 6
