The RP201x Series is a series of CMOS-based voltage regulator ICs with high output voltage accuracy, low dropout voltage, and low supply current. The series includes three modes: standby mode, fast response mode, and fast and low power auto-change mode. It also features a current limit circuit for overcurrent protection and an auto ECO mode for reduced supply current at light load. The ICs are available in SOT-23-5, SC-88A, thin DFN(PLP)1212-6, and WLCSP-4-P5 packages, allowing for high-density mounting. The series offers low power consumption and high ripple rejection.
The RICOH RP201x Series consists of CMOS-based voltage regulator ICs designed for high output voltage accuracy, low dropout voltage, and low supply current. These regulators feature a chip enable function for a standby mode with ultra-low current and include a current limit circuit to prevent destruction by overcurrent. The series offers three operating modes: Standby Mode, Fast Mode, and Auto ECO Mode (Fast and Low Power auto-change), with the latter two being selectable via the AE pin.
The RP201x Series is available in various packages including SOT-23-5, SC-88A, DFN(PLP)1212-6, and WLCSP-4-P5, enabling high-density mounting. Key features include a typical supply current of 1.0nA in low power mode, ripple rejection of 70dB at 1kHz, and an output voltage accuracy of ±1.0%. The ICs are suitable for portable communication equipment, cameras, VCRs, and other battery-powered applications.

The series has three modes: Standby Mode with the CE pin, and Fast Mode and Auto ECO Mode which are alternative with the Auto Eco pin (AE pin).
The available packages are SOT-23-5, SC-88A, thin DFN(PLP)1212-6, and WLCSP-4-P5.
The typical supply current in low power mode is 1.0nA when Vout is less than 1.85V.
Ceramic capacitors of 1.0uF or more are recommended for use with these ICs.
