About this manual

The R1162x Series consists of CMOS-based voltage regulator ICs designed for high output voltage accuracy and low supply current. These devices include a chip enable function for ultra-low standby current and a current limit circuit to prevent destruction by overcurrent. The series offers three operating modes: standby mode controlled by the CE or standby control pin, and two modes selectable via the ECO pin: Fast Transient Mode (FT) and Low Power Mode (LP).
