R1172x SERIES
SUPER LOW ON RESISTANCE / LOW VOLTAGE 1A LDO
NO.EA-122-070627

OUTLINE
The R1172x Series are CMOS-based positive volta ge regulator ICs. The R1172x Series h ave features of super
low dropout, 1A output current capability. Even the output voltage is set at 1.5V, on resistance of internal FET is
typically 0.32. Therefore, applications that require a large current at small dropout are suitable for the R1172x
series. Low input voltage is acceptable and low output voltage can be set. The minimum input voltage is 1.4V,
and the lowest set output voltage is 0.8V. Each of these ICs consists of a voltage reference unit, an error
amplifier, resistor net for setting output voltage, a current limit circuit at over-current, a chip enable circuit, a
thermal-shutdown circuit, and so on. A stand-by mode with ultra low consumption current can be realized with
the chip enable pin. The output voltage o f R1172 is fixed in the IC.
Since the packages for these ICs are SOT-23-5, SOT-89-5, HSON-6, and HSOP-6J with high power
dissipation, high density mounting of the ICs on boards is possible.

TECHNICAL NOTES
When using these ICs, consider the following p oints:
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 good frequency characteristics and ESR (Equivalent Series Resistance).
The recommendation value is as follows.

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 4.7µF 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.
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.

5.0V Output type : COUT=4.7µF (Kyocera CT21X5R475K06AB)
As an output capacitor for this IC, Ceramic capacitor is recommendable. However, other low ESR type
capacitor can be used with this IC.
For your reference, noise level is tested, and if the noise level is 40µV or less than 40µV, the ESR values are
plotted as stable area. Upper limit is described in the next five graphs, or ESR vs. Output Current. (Hatched area
is the stable area.)
