RP106N (SOT-23-5) is the non-promotion product as of April 2017.
RP106x SERIES
0.8%ACCURACY 0.7V OUTPUT 400mA LDO REGULATOR
NO.EA-180-170424
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 0.55 (at
V
OUT
½1.5V).
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.
