R1163x SERIES
3-MODE 150mA LDO REGULATOR with the Reverse Current Protection
NO.EA-118-0605
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 V
DD
pin is forced to
the output pin, the reverse current to V
DD
pin is very small (Max. 0.1µA) , so it is suitable for backup circuit.
Since the packages for these ICs are SOT-23-5, thin SON-6, and PLP1616-6 packages, high density
mounting of the ICs on boards is possible.
