RP151K SERIES  
Non-promotion  
300mA Dual LDO with VD  
OUTLINE  
NO. EA-132-130501  
The RP151 Series are CMOS-based dual voltage regulator (LDO) ICs equipped with a voltage detector (VD).  
LDO function has features of high output voltage accuracy, low supply current, low dropout, and high ripple  
rejection. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for  
setting Output Voltage, a current limit circuit, and a chip enable circuit.  
These ICs perform with low dropout voltage due to built-in transistor with low ON resistance, and a chip enable  
function prolongs the battery life of each system. The line transient response and load transient response of the  
RP151 Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication  
equipment.  
The output of built-in voltage detector is Nch open drain type.  
The output voltage of these ICs is internally fixed with high accuracy (1%). Since the packages for these ICs  
are DFN(PLP)2020-8 package, dual LDO regulators and VD are included in each packages, high density  
mounting of the ICs on boards is possible.

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:  
PCB Layout  
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.  
Connect a capacitor with a capacitance value as much as 1.0μF or more as C1 between VDD and GND pin,  
and as close as possible to the pins.  
Set the output capacitors C2 and C3 for phase compensation, as close as possible to the ICs, and make  
wiring as short as possible.  
CD external components, especially capacitor C4, as close as possible to the ICs and make wiring as short  
as possible. (Refer to TYPICAL APPLICATION)  
Phase Compensation  
In these ICs, phase compensation is made for securing stable operation even if the load current is varied.  
For this purpose, connect capacitors with a capacitance value as much as 1.0μF or more as C2 and C3 with  
good frequency characteristics and ESR (Equivalent Series Resistance) between VOUT and GND pin, and as  
close as possible to the pins.  
If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable.  
Evaluate your circuit with considering frequency characteristics.  
Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature  
characteristics are different. Evaluate the circuit with actual using capacitors.

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

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, 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.  
7.Anti-radiation design is not implemented in the products described in this document.  
8.Please contact Ricoh sales representatives should you have any questions or comments  
concerning the products or the technical information.  
For the conservation of the global environment, Ricoh is advancing the decrease of the negative environmental impact material.  
After Apr. 1, 2006, we will ship out the lead free products only. Thus, all products that will be shipped from now on comply with RoHS Directive.  
Basically after Apr. 1, 2012, we will ship out the Power Management ICs of the Halogen Free products only. (Ricoh Halogen Free products are  
also Antimony Free.)
