R1170x SERIES
OUTLINE
The R1170x Series are positive voltage regulator ICs by CMOS process. The R1170x Series have features of
high ripple rejection, low dropout voltage, high output voltage accuracy, low consumption current. Each of these
ICs consists of a voltage reference unit, an error amplifier, resistor net for setting output voltage, a current limit
circuit at short mode, a chip enable circuit, and thermal-shunt circuit. Output Voltage of R1170 is fixed in the IC.
Low consumption current by the merit of CMOS process and built-in transistors with low ON-resistance make
low dropout voltage and chip enable function prolong the battery life. These regulators are remarkable
improvement on the current regulators in terms of ripple rejection, input transient response, and load transient
response.
Maximum Output Current is large for its compact size.
Thus, the R1170x Series are suitable for various power sources for portable appliances.
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 10µF Capacitor as CL.
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. Further, refer to the Typical Characteristics No.
12.
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 as much as 10µF 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.

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 with the circuit as shown above, 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 four graphs, or ESR vs.
Output Current. (Hatched area is the stable area.)
