RP202x SERIES Low Power/Fast MODE alternative 200mA LDO REGULATOR NO.EA-279-120410 OUTLINE The RP202x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy, low dropout voltage and low supply current. These ICs perform with the chip enable function and realize a standby mode with ultra low supply current. To prevent the destruction by over current, the current limit circuit is included. The RP202 Series have 3-mode. One is standby mode with CE pin. The other two are the fast response mode (Fast Mode) and the low power mode, and switch over automatically according to the load current of the LDO. Supply current of IC itself at light load is automatically reduced. The output voltage is maintained between Fast Mode and ECO Mode. The RP202x consists of a voltage reference unit, an error amplifier, a resister net for voltage setting, and a current limit circuit. Since the packages for these ICs are SOT-23-5, SC-88A, and DFN(PLP)1010-4, 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 RP202x ELECTRICAL CHARACTERISTICS VIN=Set VOUT+1V, IOUT=1mA, CIN=COUT =0.47F, unless otherwise noted. is checked and guaranteed by design engineering at -40CTa85C.

For this purpose, use a capacitor C2 with 0.47F 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 The impedances of VDD line and GND line has to be low as possible. The high impedances may result in the unstable operation or a noise pickup. The output capacitor with 0.47F or more should be placed between VDD and GND. The line from VDD to the output capacitor, and the line from the output capacitor to GND must be wired as short as possible. The output capacitor is placed between VOUT and GND as phase compensation. The line from VOUT to the output capacitor, and the line from the capacitor to GND must be wired as short as possible.
