R1163x SERIES 3-MODE 150mA LDO REGULATOR with the Reverse Current Protection NO.EA-118-190320 OUTLINE The R1163x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy and low supply current. These ICs perform with the chip enable function and realize a standby mode with ultra low supply current. To prevent the destruction by over current, the current limit circuit is included. The R1163x Series have 3-mode. One is standby mode with CE or standby control pin. Other two modes are realized with ECO pin. Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative with ECO pin. Consumption current is reduced at Low Power Mode compared with Fast Transient Mode. The output voltage is maintained between FT mode and LP mode. Further, the reverse current protection circuit is built-in. Therefore, if a higher voltage than VDD pin is forced to the output pin, the reverse current to VDD pin is very small (Max. 0.1 A) , so it is suitable for backup circuit. Since the packages for these ICs are SOT-23-5, SON-6, and DFN(PLP)1616-6 packages, high density mounting of the ICs on boards is possible.
