RP170x SERIES
300mA 10V INPUT LDO REGULATOR
OUTLINE
NO.EA-205-130418
The RP170x Series are CMOS-based LDO regulators featuring 300mA output current. Because of the 10V
maximum input voltage, RP170x can be used in 2 cell lithium-ion battery powered portable appliances and
besides a portable equipment. The supply current is Typ. 23μA though an excellent response characteristics.

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.

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 and good ESR (Equivalent Series Resistance).
(Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for
phase compensation, the operation might be unstable. Because of this, test these ICs with as same external
components as ones to be used on the PCB.)
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.

ESR vs. Output Current
Ceramic type output capacitor is recommended for this series; however, the other output capacitors with low
ESR also can be used. 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.

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, firecontainment
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.
