Super low On resistance/ Low voltage LDO
R1173x SERIES
OUTLINE
The R1173x Series are CMOS-based positive voltage regulator ICs. The R1173x Series have features of
super low dropout, 1A output current capability, and -3mV typical load regulation at 1A. Even the output voltage
is set at 1.5V, on resistance of internal FET is typically 0.32Ω. Therefore, applications that require a large current
at small dropout are suitable for the R1173x 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 types of R1173 are fixed one in
the IC and adjustable one (R1173x001x).
Since the packages for these ICs are the SOT-89-5 package, HSON-6, or HSOP-6J, high density mounting of
the ICs on boards is possible.

Technical Notes on External Components and Typical Application
Phase Compensation
In these ICs, phase compensation is made with the output capacitor for securing stable operation even if the
load current is varied. For this purpose, use as much as a capacitor as CL. Recommendation value is as follows:

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.
Mounting on PCB
Make VDD and GND lines sufficient. If their impedance is high, a current flows, the noise picked up or unstable
operation may result. Further use a 4.7µF or more value capacitor between VDD pin and GND pin as close as
possible.
Set an Output capacitor between VOUT pin and GND pin for phase compensation as close as possible.

The Output Voltage may be adjustable for any output voltage between its 1.0V reference and its VDD setting level.
An external pair of resistors is required, as shown above.
The complete equation for the output voltage is described step by step as follows;
I1=IIC+I2 ........................................................................................(1)
I2=1.0/R2......................................................................................(2)
Thus,
I1=IIC+1.0/R2 ................................................................................(3)
Therefore,
VOUT=1.0+R1*I1 ............................................................................(4)
Put Equation (3) into Equation (4),then
VOUT=1.0+R1(IIC+1.0/R2)
=1.0(1+R1/R2)+R1*IIC ...........................................................(5)
In 2nd term, or R1*IIC will produce an error in VOUT.
In Equation (5),
IIC=1.0/RIC .....................................................................................(6)
R1*IIC=R1*1.0/RIC
=1.0*R1/RIC ...........................................................................(7)
For better accuracy, choosing R1 (<<RIC) reduces this error.

16) Stable Area: ESR limit vs. Load current (COUT:0.8V to 3.3V Output type: 4.7µF (Kyocera CM105X5R475M06AB)
5.0V Output type: 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.)
