RP111x Series
Good Transient Response Low Voltage 500mA LDO
NO.EA-241-150204
OUTLINE
The RP111x Series are CMOS-based LDO regulators featuring 500mA output current. The input voltage is as
low as 1.4V and the output voltage can be set from 0.7V. Due to a built-in 0.46Ω (at VOUT=2.8V) on-resistor, RP111x
can provide a low dropout voltage. RP111x also features an excellent line transient response, ripple rejection at
75dB, and low noise. The output voltage accuracy is as high as ±0.8% and the temperature drift coefficient of
output voltage is low at ±30ppm/C. The accuracy of the output voltage of RP111x includes the temperature
characteristics and the load transient response has been improved. The typ. and max value of under/overshoot
for various output current are shown in the typical characteristics in the datasheet, therefore the accuracy of the
output voltage estimation will be easy on the actual operating cases.
In addition to a fold-back protection circuit built into conventional regulators, RP111x contains a thermal
shutdown circuit and an inrush current limit circuit. SOT-23-5 and SOT-89-5 packages, a 1.2mm square
DFN1212-6 package are available.

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.

Under normal conditions, please connect the VOUT pin to the VFB pin. However, in the case of using the
Adjustable Output Voltage Type, please follow the " Notes on the Adjustable Output Voltage Type Settings".
TECHNICAL NOTES
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 1.0F or more capacitor C2.
In case of using a tantalum capacitor, the output may be unstable due to inappropriate ESR. Therefore, the full
range of operating conditions for the capacitor in the application should be considered.
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.

Please set 3.6V or less for the Adjustable Output Voltage Type. Also, please use 16k or less for R2 resistor.
Phase Compensation
Similar to the Fixed Output Voltage Type, Phase compensation is made for the Adjustable Output Voltage Type
for securing stable operation even if the load current is varied. For this purpose, use a 4.7F or more capacitor
C2 between VOUT pin and GND pin, and as close as possible to the pins.
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.
Transient Response
When using the Adjustable Output Voltage Type, the transient response could be affected by the external
resistors. Evaluate the circuit taking the actual conditions of use into account.

transient response. The load transient response indicated under the Electrical Characteristics is guaranteed by
design based on the condition when IOUT changes from 1mA to 250mA or 250mA to1mA. The output voltage

The graphs shown above are reference data.
For the better transient response, a capacitor with higher capacitance is recommended and the wire
impedance of GND and VOUT should be minimized as possible.
The transient response characteristics depend on the external parts and PCB layout. Therefore, the
operating conditions for the transient response in the application should be considered and evaluation is
necessary.

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.
