OUTLINE
The RP130x Series are CMOS-based positive voltage regulator ICs with high ripple rejection, low dropout
voltage, high output voltage accuracy and extremely low supply current. Each of these ICs consists of a voltage
reference unit, an error amplifier, a resistor-net for voltage setting, a short current limit circuit and a chip enable
circuit.
These ICs have an excellent low supply current performed by CMOS process, moreover they perform with low
dropout voltage due to built-in low ON-resistance. A chip enable function prolongs the battery life.
The input transient response, the load transient response and the ripple rejection have been improved in the
RP130x Series compared with the conventional products. Besides achieving low supply current (Typ.38μA).
The range of the operation voltage is capable from 1.7V to 6.5V and the range of the output voltage is capable
from 1.2V to 5.3V for this product, which is wider range as our conventional product R1114x series.
The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are
DFN(PLP)1010-4, SOT-23-5 and SC-82AB, therefore high density mounting of the ICs on boards is possible.

Ceramic Capacitor C2 0.47μF MURATA GRM155B30J474KE18B
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 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 high, noise pickup or unstable operation may result.
Connect a capacitor C1 with a capacitance value as much as 0.47μF 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
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 40μV (Avg.) are marked as the hatched area in the graph.
