R1160x SERIES
3-MODE 200mA LDO REGULATOR
NO.EA-083-140530
OUTLINE
The R1160x Series consist of 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 R1160x Series have 3-mode. One is standby mode with CE or
standby control pin. 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 to 1/10 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 and SON-6 packages, 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.

R1160x
Series
C1
C2
CE
ECO GND
(External Components)
C1: Ceramic Capacitor 1μF
C2: Tantalum Capacitor 2.2μF
When using these ICs, consider the following points:
1. 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 1.0μF 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.
2. 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 2.2μF 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.)
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.
If you use a ceramic type output capacitor, please connect about 1Ω resistor in series for the stability of output
voltage.
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:
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.
