R1122N SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-060-111027
OUTLINE
The R1122N Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current, low ON-resistance, and high Ripple Rejection. Each of these voltage regulator ICs consists of a
voltage reference unit, an error amplifier, resistors, 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 R1122N 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
(Mini-mold) package , 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.

In these ICs, fluctuation of the output voltage, VOUT is detected by feed-back registers R1, R2, and the result is
compared with a reference voltage by the error amplifier, so that a constant voltage is output.
A current limit circuit for protection at short mode, and a chip enable circuit, are included.

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 capacitor COUT with good frequency characteristics and ESR (Equivalent Series
Resistance).
(Note: When the additional ceramic capacitors are connected to the output pin with the output capacitor for
phase compensation, the operation might be unstable. Because of this, test these ICs with the same external
components as the ones to be used on the PCB.)
Recommended Capacitors ; GRM40X5R225K6.3 (Murata)
GRM40-034X5R335K6.3 (Murata)
GRM40-034X5R475K6.3 (Murata)
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, picking up the noise or unstable operation may
result. Connect a capacitor with a capacitance of 2.2μF or more between VDD and GND pin as close as possible.
Set external components, especially output capacitor as close as possible to the ICs and make wiring as short
as possible.

Measuring Circuit for white noise; R1122N301B
The relationship between IOUT (output current) and ESR of the output capacitor is shown in the graphs below.
The conditions when the white noise level is under 40μV (Avg.) are indicated by the hatched area in the graph.
(Note: When additional ceramic capacitors are connected to the output pin with the output capacitor for phase
compensation, operation might be unstable. Because of this, test these ICs with the same external components
as the ones to be used on the PCB.)
<Measuring Conditions>
(1)VIN=VOUT+1V
(2)Frequency band: 10Hz to 1MHz
(3)Temperature: 25°C
