R1162x SERIES
Non-promotion
3-MODE 150mA LDO REGULATOR
NO.EA-110-130415
OUTLINE
The R1162x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy and low
supply current. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier,
resistors for setting output voltage, a current limit circuit, and so on. The output voltage is internally fixed with
high accuracy.
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 R1162x 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.
Since the packages for these ICs are SOT-23-5 and SON1612-6 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.
