R1163N Series
3-Mode 150 mA LDO Regulator with the Reverse Current Protection for Automotive Applications
NO.EC-118-131219
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 package for these ICs is SOT-23-5 package, the high density mounting of the ICs on boards is
possible.

* Auto-discharge function quickly lowers the output voltage to 0V, when the chip enable signal is switched from the active
mode to the standby mode, by releasing the electrical charge accumulated in the external capacitor.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent
damages and may degrade the life time and safety for both device and system using the device in the field.
The functional operation at or over these absolute maximum ratings is not assured.

RECOMMENDED OPERATING RATINGS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating ratings. The semiconductor devices cannot operate normally over the recommended
operating ratings, even if when they are used over such ratings by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended
operating ratings.
