R1114N Series
Low Noise 150 mA LDO Regulator for Automotive Applications
NO.EC-094-131219
OUTLINE
The R1114x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply
current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an
error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The line transient response and load
transient response of the R1114x Series are excellent, thus these ICs are very suitable for the power supply for
hand-held communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the package for these ICs is SOT-23-5, the
high density mounting of the ICs on boards is possible.

RECOMMENDED OPERATING RATINGS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating ratings. The semiconductor devices cannot operate normally over the recommended
operating ratings, even if when they are used over such ratings by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended
operating ratings.

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 COUT with good frequency characteristics and ESR (Equivalent Series Resistance).
Recommended C2 Values
Output Voltage
RecommendedC2 values
VOUT ≤ 2.4V
2.5V ≤ VOUT
1.0μF or more
0.47μF or more
When using a tantalum type capacitor and the ESR value of the capacitor is large, the output might be unstable.
Evaluate a circuit including consideration of frequency characteristics.
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor 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, as close as possible to the ICs, and make wiring as
short as possible.

When a sudden surge of electrical current travels along the VOUT pin and GND due to a short-circuit, electrical
resonance of a circuit involving an output capacitor and a short circuit inductor generates a negative voltage and
may damage the device or the load devices. Connecting a schottky diode (D1) between the VOUT pin and GND
has the effect of preventing damage to them.

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, use a capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance)
of which is in the range described as follows:
CE
VOUT
Ceramic
Cap.
R1114xxx1B/D
Spectrum
Analyzer
S.A.

IOUT
Measuring Circuit for white noise; R1114xxx1B/D
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.
(Note: If 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.)
<Measurement conditions>

(2) Frequency Band: 10Hz to 2MHz
(3) Temperature: −40°C to 25°C
