RP201x SERIES
3-MODE 150mA LDO REGULATOR
NO.EA-234-160617
OUTLINE
The RP201x Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy, low
dropout voltage and low supply current. These ICs perform with the chip enable function and realize a standby
mode with ultra low supply current. To prevent the destruction by over current, the current limit circuit is included.
The RP201x Series have 3-mode. One is standby mode with CE pin. Other two modes are realized with ECO
Function. Fast Response Mode (Fast Mode) and Fast and Low Power auto-change Mode (Auto ECO Mode) are
alternative with Auto Eco pin (AE pin). Supply current of IC itself at light load is automatically reduced at Auto
ECO Mode compared with Fast Mode. The output voltage is maintained between Fast Mode and Auto ECO
Mode.
Without AE pin type is also available. It is an LDO regulator with Auto ECO mode. (RP201Z in WLCSP.)
Since the packages for these ICs are SOT-23-5, SC-88A, thin DFN(PLP)1212-6, and WLCSP-4-P5, high
density mounting of the ICs on boards is possible. RP201Q (SC-88A), RP201K (DFN(PLP)1212-6) and RP201N
(SOT-23-5) has AE pin, then if the AE pin is "H", Fast Mode is available. If the AE pin is set at "L" level, Auto ECO
Mode operation is available.

All of units are tested and specified under load conditions such that Tj≈Topt25C except for Ripple Rejection,
Output Voltage Temperature Coefficient.
1) The value of supply current is excluding the Pull-down constant current of CE Pin and AE Pin.
2) The maximum Input Voltage of the ELECTRICAL CHARACTERISTICS is 5.25V. In case of exceeding this
specification, the IC must be operated on condition that the Input Voltage is up to 5.5V and the total
operating time is within 500hrs.
3) Applied to RP201K/N/Q
4) VIN 1.4V condition is dominant against this specification.
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 1.0F or more and good 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 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.
Impedance of Input Pin (CE Pin and AE Pin)
In those ICs, there is a pull-down constant current in the CE Pin and the AE Pin.
However, if those pins are floating and wired long that produce the noise environment, it might miss-operation of
ICs. For this purpose, please make sure enough evaluation of ICs.

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 40V (Avg.) are marked as the hatched area in the
graph.
