*RP173Q(SC-88A) is the non-promotion product as of March 2020. RP173x Series 11 V Input 150 mA LDO No. EA-256-200430 OUTLINE The RP173x is a voltage regulator featuring 150 mA output and low supply current of Typ. 2.0 µA. It consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit, a chip enable circuit and a Reverse Current Protection Circuit. RP173x is suitable for the power source such as the equipment being in the standby-mode. The A version with CE input pin has reduced CE pull-up resistance to make its supply current ultra low. The RP173x has Max.11 V Input voltage and is applicable to the portable communication equipment that requires the 2-cell Li-ion battery. Also it is applicable to the non-portable communication equipments. As the RP173x includes Reverse Current Protection Circuit, there is little leakage current, if it is used as back-up circuit. Packages are available in SOT-23-5, SC-88A, and 1-mm square DFN(PLP)1010-4 packages. High density mounting of the ICs on boards is possible.

RP173x No. EA-256-200430 THEORY OF OPERATION REVERSE CURRENT PROTECTION CIRCUIT The RP173 Series include a Reverse Current Protection Circuit, which stops the reverse current from VOUT pin to VDD pin or to GND pin when VOUT becomes higher than VIN. Usually, the LDO using Pch output transistor contains a parasitic diode between VDD pin and VOUT pin. Therefore, if VOUT is higher than VIN, the parasitic diode becomes forward direction. As a result, the current flows from VOUT pin to VDD pin. The ICs of this series switches the mode to the reverse current protection mode before VIN becomes lower than VOUT by connecting the parasitic diode of Pch output transistor to the backward direction, and connecting the gate to VOUT pin. As a result, the Pch output transistor is turned off and the all the current pathways from VOUT pin to GND pin are shut down to maintain the reverse current lower than [IREV] of the Electrical Characteristics. Switching to either the normal mode or to the reverse current protection mode is determined by the magnitude of VIN voltage and VOUT voltage. For the stable operation, offset and hysteresis are set as the threshold. The detection/ release thresholds of both normal and reverse current protection modes are specified by [VREV_DET] and [VREV_REL] of the Electrical Characteristics. Therefore, the minimum dropout voltage under the small load current condition is restricted by the value of [VREV_REL]. Fig.1 and Fig.2 show the diagrams of each mode, and Fig.3 shows the load characteristics of each mode. When giving the VOUT pin a constant-voltage and decreasing the VIN voltage, the dropout voltage will become lower than the [VREV_DET]. As a result, the reverse current protection starts to function to stop the load current. By increasing the dropout voltage higher than the [VREV_REL], the protection mode will be released to let the load current to flow. If the dropout voltage to be used is lower than [VREV_REL], the detection and the release may be repeated. The operation coverage of the Reverse Current Protection Circuit is VOUT ≥ 1.5V. However, under the condition of VIN=0V, always the reverse current protection mode is operating.

For this purpose, use a 0.1µF or more capacitor C2. In case of using a tantalum capacitor, the output may be unstable due to inappropriate ESR. Therefore, the full range of operating conditions for the capacitor in the application should be considered. 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 0.1µF 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. 11 *RP173Q(SC-88A) is the non-promotion product as of March 2020.
