RP110x SERIES
150mA Low Supply Current LDO REGULATOR
NO.EA-239-111020
OUTLINE
The RP110x Series is a voltage regulator (LDO) IC, which has been developed using the CMOS process
technology, with high output voltage accuracy, ultra-low supply current, and low ON-resistance transistor. The IC
contains the following components: a voltage reference unit, an error amplifier, a resistor-net for output voltage
setting, a current limit circuit for preventing short-circuit, a soft-start circuit, and a chip enable circuit.
By minimizing the supply current to 1µA, the IC is able to prolong the battery life of each system. The external
capacitor is 0.1µF with phase compensation. The IC also has a constant slope circuit as a soft-start circuit, which
does not require any external capacitor. It minimizes the inrush current and prevents the output voltage
overshoot at the start-up.
In addition to the small packaged SOT-23-5 and SC-88A, the RP110x Series offers the ultra-small
DFN(PLP)0808-4 package and DFN1010-4, which enables the high density mounting of LDO regulator.

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 good frequency characteristics and 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 0.1μF 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.

RP110x
■ Constant Slope Circuits
The RP110x Series is equipped with a constant slope circuit as a soft-start circuit, which allows the output
voltage to start up gradually when the CE is turned on.
The constant slope circuit minimizes the inrush current at the start-up and also prevents the overshoot of the
output voltage.
The capacitor to create the start-up slope is built in the IC that does not require any external components. The
start-up time and the start-up slope angle are fixed inside the IC.
If the capacitance of the external output capacitor (COUT) becomes more than the certain capacitance, the
output current limit circuit minimizes the incoming current of the output capacitor at the start-up. As a result, the
start-up time becomes longer and the start-up slope angle becomes more gentle. As “Inrush Current
Characteristics Example” below shows, if the COUT is less than 4.7µF, the constant slope circuit easily starts to
function at the start-up, likewise, if the COUT is over 10µF, the output current limit circuit easily starts to function at
the start-up. The boundary point of using these two circuits is inversely proportional to the output voltage. If the
output voltage is higher, the output current limit circuit easily starts to function even if the COUT capacitance is
small. For more details, please refer to the graph 14 of “Inrush Current Characteristics Example”.

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.
Measurement conditions
Frequency Band : 10Hz to 2MHz
Temperature
: −40°C to 85°C
Hatched Area : Noise level is under 40μV(Avg.)
