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.

μA) , 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.
