RP106x SERIES
0.8%ACCURACY 0.7V OUTPUT 400mA LDO REGULATOR
NO.EA-180-131017
OUTLINE
The RP106x 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. In addition to SOT-23-5 and SC-88A packages, a
0.69mm square WLCSP-4-P5 package and a 1.2mm square DFN(PLP)1212-6 are also available.

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.
