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
VOUT=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.

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.

TECHNICAL NOTES
When using these ICs, consider the following points:
Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, use a capacitor C2 with 1.0μF or more.
If a tantalum capacitor is used, and its ESR (Equivalent Series Resistance) of C2 is large, the loop oscillation
may result. Because of this, select C2 carefully considering its frequency characteristics.
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor C1 with a capacitance value as much as 1.0μF or more between VDD and GND pin, and as
close as possible to the pins.
Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring
as short as possible.
Impedance of Input pin
CE pull-down constant current circuit is built in the RP106x.
However, if the CE pin is floating and the wiring is long, the malfunction may occur by noise. Therefore, fully
evaluation on the actual PCB is necessary.

NO.EA-180-131017
8
CONSTANT SLOPE CIRCUITS
The RP106x Series is equipped with a constant slope circuit as a soft-start circuit, which allows the output
voltage to start up gradually when the CE is turned on.
The constant slope circuit minimizes the inrush current at the start-up and also prevents the overshoot of the
output voltage.
The capacitor to create the start-up slope is built in the IC that does not require any external components. The
start-up time and the start-up slope angle are fixed inside the IC. For more details, please refer to the graph 15 of
“Inrush Current Characteristics Example”.

ESR vs. Output Current
When using these ICs, consider the following points:
The relations between IOUT (Output Current) and ESR of an output capacitor are shown below.
The conditions when the white noise level is under 40μV (Avg.) are marked as the hatched area in the graph.
Measurement conditions
Frequency Band: 10Hz to 3MHz
Temperature : −40°C to 85°C
C1, C2 : 1.0μF MURATA GRM155B31A105KE15
If other than ceramic capacitors such as tantalum, the ESR of the capacitor might be higher than expected.
This graph shows the stable area with ESR limit. In the actual evaluation, we used Murata
GRM155B31A105KE15, therefore, bias characteristics of the same kind of ceramic capacitors are
considered.
