R1131x SERIES
Low Voltage 300mA LDO REGULATOR
NO.EA-116-130411
OUTLINE
The R1131x Series are CMOS-based low voltage regulator ICs with output voltage range from 0.8V to 3.3V.
The minimum operating voltage is 1.4V. Each of these voltage regulator ICs consists of a voltage reference unit,
an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit.
To prevent the destruction by over current, current limit circuit is included. Standby mode realizes ultra small
consumption current.
The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are
SOT-23-5, SON-6, and HSON-6 (Non-promotion), high density mounting of the ICs on boards is possible.

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, be sure to use a 1.0μF or more capacitor COUT with good frequency characteristics and ESR
(Equivalent Series Resistance).
(Note: If a tantalum capacitor is connected to the Output pin for phase compensation, if the ESR value of the
capacitor is too large, the operation might be unstable. Because of this, test these ICs with as same external
components as ones to be used on the PCB.)
Chip capacitor characteristics of Bias dependence and Temperature characteristics may vary depending on its
size, manufacturer, and part number.
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, pick-up the noise or unstable operation may
result. Connect a capacitor with as much as 1.0μF capacitor between VDD and GND pin as close as possible.
Set external components, especially the output capacitor, 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:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, be sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent Series
Resistance) of which is in the range described as follows:
The relations between IOUT (Output Current) and ESR of 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.
<Test conditions>
