Transcription

1 SERIES 3mA LDO REGULATOR OUTLINE The RPx Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, a chip enable circuit, and so on. RPx features a minimum input voltage from.v and the output voltage, which can be set from.8v to 3.6V (in.v step). The output voltage of these ICs is internally fixed. These ICs perform with low dropout voltage due to built-in transistor with low ON resistance. Low supply current and a chip enable function prolong the battery life of each system. The ripple rejection, 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. Since the packages for these ICs are DFN(PLP)-, SC-88A, SOT-3-5, therefore high density mounting of the ICs on boards is possible. FEATURES Supply Current... Typ. 5µA Standby Current...

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.

7 TYPICAL APPLICATIONS VDD VOUT VOUT C RPx Series C CE GND (External Components) C Ceramic.µF MURATA: GRM55B3A5KE5 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. 7
