R1180x SERIES
150mA LDO REGULATOR
OUTLINE
NO.EA-105-111027
The R1180x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current, and low ON-resistance. Each of these ICs consists of a voltage reference unit, an error amplifier,
resistor-net for voltage setting, a current limit circuit which prevents the destruction by excess current, and so on.
The output voltage of these ICs is fixed with high accuracy. B version has a chip enable pin, therefore ultra-low
consumption current standby mode can be realized with the pin.
Since the packages for these ICs are SOT-23-5 (R1180N Series), SC-82AB (R1180Q Series), and SON1612-6
(R1180D Series), therefore high density mounting of the ICs on boards is possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
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.

ESR vs. Output Current
The relations between IOUT (Output Current) and ESR of an output capacitor are shown above. The conditions
when the white noise level is under 40μV (Avg.) are marked as the hatched area in the graph.
<Measurement conditions>
(1) VIN=VOUT+1V
(2) Frequency Band: 10Hz to 2MHz (BW=30Hz)
(3) Temperature: −40°C to 85°C
