R1115Z SERIES
Non-promotion
LOW NOISE 150mA LDO Regulator
NO.EA-107-130410
OUTLINE
The R1115Z Series are CMOS-based voltage regulator ICs with extremely low supply current, low
ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier,
resistor-net for voltage setting, a current limit circuit, and a chip-enable circuit.
These ICs perform with low dropout voltage and a chip-enable function. The line transient response and load
transient response of the R1115Z Series are excellent, thus these ICs are very suitable for the power supply for
hand-held communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the package for these ICs is WLCSP-4-P4,
therefore 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.
