The R1191x Series are CMOS-based manual mode switching 16V input voltage regulators with ECO pin featuring 300mA output. By inputting control signals to the ECO pin, the mode of the regulator can be switched to low power mode or fast response mode, thus making both active and sleep modes available for the system. The built-in reverse current protection circuit prevents the current flow from VOUT to VDD when VOUT is higher than VDD. This feature makes the product ideally suited for backup circuit. Standby mode and auto-discharge function are also available (see Selection Guide). Ceramic capacitors can be used.
The Ricoh R1191x Series is a low supply current voltage regulator with high output voltage accuracy and a maximum operating voltage of 16V. These ICs can switch between fast mode and low power mode using the ECO pin without changing the output voltage. Key features include reverse current protection, built-in fold-back protection, and thermal shutdown circuits, making them suitable for back-up circuits and digital home appliances.
