RP101x SERIES
0.6% ACCURACY LOW NOISE 300mA LDO REGULATOR
NO.EA-167-160425
OUTLINE
The RP101x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely
low supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage
reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The line transient response and
load transient response of the RP101x Series are excellent, thus these ICs are very suitable for the power
supply for hand-held communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are SOT-23-5
and DFN(PL)1612-4 (t=0.6mm type) or DFN(PL)1612-4B (t=0.4mm type), therefore high density mounting of
the ICs on boards is possible.

) The maximum Input Voltage of the ELECTRICAL CHARACTERISTICS is 5.25V. In case of exceeding this
specification, the IC must be operated on condition that the Input Voltage is up to 5.5V and the total operating
time is within 500hrs.
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 capacity.
Ceramic capacitors have different temperature characteristics and bias characteristics depending on their
dimensions and manufacturers. If the setting voltage is 2.5V or more and the capacitor’s dimensions for VOUT
equal to 1.0mm by 0.5mm or smaller than that, the capacitance value might be extremely low. As a result, the
capacitance might be much less than expected. In such cases, the operation might be unstable at low
temperature. (20C or less) In that case, use a larger capacity, or a large dimensions’ capacitor. (For example
1.6mm by 0.8mm)
If a tantalum capacitor is selected as an output capacitor, large ESR may be a cause of unstable operation.
Evaluate the operation of PCB with considerable 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.

for the products. The release of such information is not to be construed as a warranty of or a grant of license under
our company's or any third party's intellectual property rights or any other rights.
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 our sales or our distributor before attempting to use
AOI.
11. Please contact our sales representatives should you have any questions or comments concerning the products or
the technical information.
