RP116Z SERIES
0.8%ACCURACY 0.7V OUTPUT 400mA LDO REGULATOR
NO.EA-281-111020
OUTLINE
The RP116Z Series are low voltage 400mA voltage regulator. These ICs had been further improved of
low-voltage capability compared with previous low-voltage product.
The input voltage is as low as Min. 1.0V and the output voltage can be set from 0.7V. The output voltage
accuracy has been improved to
±0.8%
and due to a built-in transistor with low on-resistance of 0.55Ω (at
V
OUT
=1.5V).
Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, and
a current limit circuits for over-current for the destruction prevention by the over-current.
The CE pin can switch the regulator to standby mode.
The RP116Z is available in the small and thin WLCSP-4-P7 package (0.69mm square, 0.36mm thickness and
0.4mm pitch), consequently providing a high density mounting.

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.
