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 lowvoltage 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
VOUT1.5V).
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 1.0F 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 1.0F 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.

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 40V (Avg.) are marked as the hatched area in the graph.
Measurement conditions
Frequency Band: 10Hz to 3MHz
Temperature
: 40C to 85C
C1, C2
: 1.0F 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.

5. The products listed in this document are intended and designed for use as general electronic components in standard
applications (office equipment, telecommunication equipment, measuring instruments, consumer electronic products,
amusement equipment etc.). Those customers intending to use a product in an application requiring extreme quality
and reliability, for example, in a highly specific application where the failure or misoperation of the product could result
in human injury or death (aircraft, spacevehicle, nuclear reactor control system, traffic control system, automotive and
transportation equipment, combustion equipment, safety devices, life support system etc.) should first contact us.
6. We are making our continuous effort to improve the quality and reliability of our products, but semiconductor products
are likely to fail with certain probability. In order to prevent any injury to persons or damages to property resulting from
such failure, customers should be careful enough to incorporate safety measures in their design, such as redundancy
feature, fire containment feature and fail-safe feature. We do not assume any liability or responsibility for any loss or
damage arising from misuse or inappropriate use of the products.
7. Anti-radiation design is not implemented in the products described in this document.
8. The X-ray exposure can influence functions and characteristics of the products. Confirm the product functions and
characteristics in the evaluation stage.
9. WLCSP products should be used in light shielded environments. The light exposure can influence functions and
characteristics of the products under operation or storage.
10. There can be variation in the marking when different AOI (Automated Optical Inspection) equipment is used. In the
case of recognizing the marking characteristic with AOI, please contact Ricoh sales or our distributor before attempting
to use AOI.
11. Please contact Ricoh sales representatives should you have any questions or comments concerning the products or
the technical information.
