R1170x SERIES
800mA LDO REGULATOR
NO.EA-084-111027
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.

Tab and tab suspension leads in the
parts are GND level.
(They are connected to the reverse side of the IC.)
The tab is better to be connected to the GND, but leaving it open is also acceptable.
The tab suspension leads should be open and do not connect to other wires or land patterns.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
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.
