Ricoh R1163x Series 3-Mode 150mA LDO Regulator Datasheet
The Ricoh R1163x Series consists of CMOS-based voltage regulator ICs designed for high output voltage accuracy and low supply current. These ICs include a chip enable function for a standby mode with ultra-low supply current and a built-in current limit circuit to prevent destruction by over-current. The series offers three operating modes: Standby Mode, Fast Transient Mode (FT mode), and Low Power Mode (LP mode), with the latter two being selectable via the ECO pin. The output voltage is maintained between FT and LP modes, and a reverse current protection circuit is built-in to ensure suitability for backup circuits. This manual is written in Japanese.

From: Ricoh R1163x Series 3-Mode 150mA LDO Regulator Datasheet
What is the function of the ECO pin?
The ECO pin allows the mode of the regulator to be switched to low power mode or fast response mode.
Does this regulator have reverse current protection?
Yes, the built-in reverse current protection circuit prevents current flow from Vout to Von when Vout is higher than Von.
