RICOH RP107x Series Data Manual
Summary
The RP107x Series is a high-efficiency CMOS Low Dropout Regulator designed for powering sensitive, battery-operated electronics. This regulator provides reliable 200mA output while maintaining ultra-low standby current (down to 9.5μA). The manual details comprehensive technical specifications, including voltage ranges, dropout characteristics, and selecting among various packages (WLCSP, DFN) and modes—including auto-discharge for system reset. Ideal for engineers designing portable communication gear, IoT devices, or other low-power applications requiring maximum efficiency and small form factors.

RP107x Series Output Capacitor-less 200m A LDO
The RP107x Series are CMOS-based LDO regulators featuring 200m A output. Since the output capacitor and noise bypass capacitor are able to be reduced and the packages are small DFN(PLP)1212-6, WLCSP-4-P5, and SC-88A, high density mounting on boards are possible. The input voltage (VIN) is as low as Min.1.4V and the output voltage can be set from 1.0V. Supply current is as low as 9.5μA compared to existing lines. The CE pin can switch the regulator to standby mode.

Frequently Asked Questions
What is the minimum input voltage required for this regulator?
The input voltage (VIN) can be as low as 1.4V.
Can I reduce the output capacitor size with this component?
Yes, since both the output and noise bypass capacitors can be reduced, high density mounting is possible.
How effective is the regulator at rejecting ripple?
It offers a Ripple Rejection (RR) of Typ. 60dB at 1kHz when VOUT is above 2.5V.
What are the available packages/mounting options?
Packages include WLCSP-4-P5, DFN(PLP)1212-6, SC-88A, and SOT-23-5.
