R1130x SERIES
300mA LDO REGULATOR
NO.EA-078-120404
OUTLINE
The R1130x Series are CMOS-based voltage regulator (VR) ICs. VR function has features of high ripple
rejection, low dropout voltage, high output voltage accuracy, and ultra-low supply current. Each of these ICs
consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, and a current limit
circuit. Each of the R1130xxxxA/B type includes also a chip enable circuit.
The output voltage of the R1130xxxxC type is adjustable with external resistors.
The output voltage of R1130xxxxA/B is fixed in the IC. Low supply current by the merit of CMOS process and
built-in transistors with low ON-resistance make low dropout voltage. These regulators in the R1130x Series 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 R1130x Series are suitable for power supply for CD-drives, DVD-drives, and so forth.
Since the packages for these ICs are the SOT-89-5 package or HSON-6 (Discontinued), high density
mounting of the ICs on boards is possible.

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.
