R1163x SERIES
3-MODE 150mA LDO REGULATOR with the Reverse Current Protection
NO.EA-118-140724
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. 0.1μA) , 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.

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

TECHNICAL NOTES
When using these ICs, consider the following points:
Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, be sure to use a 0.47μF or more ceramic capacitor C2.
(Test these ICs with as same external components as ones to be used on the PCB.)
When a tantalum capacitor is used with this IC, if the equivalent series resistor (ESR) of the capacitor is large,
output voltage may be unstable.
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor C1 with as much as 1.0μF capacitor between VDD and GND pin as close as possible.
Set external components such as an output capacitor C2, as close as possible to the ICs and make wiring as
short as possible.

TECHNICAL NOTES
When using these ICs, consider the following points:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, be sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent Series
Resistance) in the range described as follows:
The relations between IOUT (Output Current) and ESR of Output Capacitor are shown below. The conditions
when the white noise level is under 40µV (Avg.) are marked as the hatched area in the graph.
