RP130x-Y Series
Low Noise 150mA LDO Regulator for Industrial Applications
NO.EA-336-211001
OUTLINE
The RP130x is a CMOS-based positive voltage regulator IC with high ripple rejection, low dropout voltage, high
output voltage accuracy and extremely low supply current. The RP130x consists of a voltage reference unit, an
error amplifier, a resistor network for voltage setting, a short current limit circuit, and a chip enable circuit.
The RP130x has low supply current characteristics in the CMOS process. In addition, the RP130x can supply
a low dropout voltage, which becomes the smallest difference between the input voltage and output voltage by
having a low on-resistance and also can achieve the battery's long life by a chip enable function.
When compared with the conventional products of high-speed type, the RP130x achieves low consumption
current of 38µA (Typ.) while improving the input transient response, the load transient response, and the ripple
rejection.
The RP130x supports two package types: DFN(PLP)1010-4 and SOT-23-5. By the adoption of the ultracompact DFN(PLP)1010-4, the RP130x can achieve a higher density mounting than ever.
This is a high-reliability semiconductor device for industrial applications (-Y) that has passed both the screening
at high temperature and the reliability test with extended hours.

RECOMMENDED OPERATING CONDITIONS
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 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
Phase Compensation
In the ICs, phase compensation is made for securing stable operation even if the load current is varied. For this
purpose, use a capacitor C2 with 0.47µF 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 too high, noise pickup or unstable operation may result.
Connect 0.47µF or more of the capacitor C1 between the VDD and GND, and as close as possible to the pins.
In addition, connect the capacitor C2 between VOUT and GND, and as close as possible to the pins.

GND
When a sudden surge of electrical current travels along the VOUT pin and GND due to a short-circuit, electrical
resonance of a circuit involving an output capacitor (C2) and a short circuit inductor generates a negative voltage
and may damage the device or the load devices. Connecting a schottky diode (D1) between the VOUT pin and
GND has the effect of preventing damage to them.

ESR vs. Output Current
The RP130x is recommended to use a ceramic type capacitor, but the RP130x can be used other capacitors of
the lower ESR type. The relation between the output current (IOUT) and the ESR of output capacitor is shown
below.
Measurement conditions
Frequency Band: 10Hz to 3MHz
Measurement Temperature: − 40°C to 85°C
Hatched area: Noise level is 40μV (average) or below
Ceramic Capacitor: C1 = Ceramic 0.47μF, C2 = 0.47μF

consent of Ricoh.
3. Please be sure to take any necessary formalities under relevant laws or regulations before exporting or otherwise
taking out of your country the products or the technical information described herein.
4. The technical information described in this document shows typical characteristics of and example application circuits
for the products. The release of such information is not to be construed as a warranty of or a grant of license under
Ricoh'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 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.
