RICOH RP201x Series 3-Mode 150mA LDO Regulator Datasheet
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.

Which packages are available for the RP201x Series?
The available packages are SOT-23-5, SC-88A, thin DFN(PLP)1212-6, and WLCSP-4-P5.
From: RICOH RP201x Series 3-Mode 150mA LDO Regulator Datasheet
What is the ECO function in the RP201x Series?
The ECO function allows the regulator to switch automatically between fast response mode and low power mode depending on the system load.
