R1161x SERIES
3-MODE 300mA LDO REGULATOR
OUTLINE
NO.EA-106-130415
The R1161x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply
current, and low ON-resistance. 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.
These ICs perform with low dropout voltage and a chip enable function. To prevent the destruction by over
current, current limit circuit is included. The R1161x Series have 3-mode. One is standby mode with CE or
standby control pin. Standby mode realizes ultra small consumption current off mode. Other two modes are
realized with ECO pin. Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative with
ECO pin. Consumption current is reduced at Low Power Mode compared with Fast Transient Mode. Output
voltage is maintained between FT mode and LP mode.
The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are
SOT-23-5, SON-6 (Non-promotion), and HSON-6 (Non-promotion), high density mounting of the ICs on boards
is possible.

∗) Tab and tab suspension leads are GND level. (They are connected to the reverse side of the IC.)
The tab is better to be connected to the GND, but leaving it open is also acceptable.
The tab suspension leads should be open and do not connect to other wires or land patterns.

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

ECO
When using these ICs, consider the following points:
1.Mounting on PCB
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor C1 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.
2.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 more capacitor C2 with good frequency characteristics and ESR
(Equivalent Series Resistance).
Output Voltage
Recommended Value of C2
1.0μF or more Tantalum Capacitor

VOUT

(Note: When the additional ceramic capacitors are connected to the Output Pin with 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.)
If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable.
Evaluate your circuit with considering frequency characteristics.
Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature
characteristics are different. Evaluate the circuit with actual using capacitors.

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 output current is varied.
For this purpose, be sure to use a capacitor COUT with good frequency characteristics and ESR (Equivalent
Series Resistance) 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>
(1) Frequency band: 10Hz to 2MHz
(2) Temperature: 25°C
