1 RPx SERIES.6% ACCURACY LOW NOISE ma LDO REGULATOR OUTLINE NO.EA The RPx 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, 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. The line transient response and load transient response of the RPx 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--5 and DFN(PLP)6- (t.6mm type) or DFN(PLP)6-B (t.mm type), therefore high density mounting of the ICs on boards is possible. FEATURES Supply Current...

In case of exceeding this specification, the IC must be operated on condition that the Input Voltage is up to 5.5V and the total operating time is within 5hrs. 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. 5

6 RPx NO.EA TYPICAL APPLICATION VDD VOUT VOUT C RPx Series C CE GND (External Components) C. F MURATA: GRM55BA5KE5 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. F or more capacity. Ceramic capacitors have different temperature characteristics and bias characteristics depending on their dimensions and manufacturers. If the setting voltage is.5v or more and the capacitor s dimensions for VOUT equal to.mm by.5mm or smaller than that, the capacitance value might be extremely low. As a result, the capacitance might be much less than expected. In such cases, the operation might be unstable at low temperature. ( C or less) In that case, use a larger capacity, or a large dimensions capacitor. (For example.6mm by.8mm) If a tantalum capacitor is selected as an output capacitor, large ESR may be a cause of unstable operation. Evaluate the operation of PCB with considerable frequency characteristics. 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. F 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
