R1130x SERIES

300mA LDO REGULATOR

OUTLINE

NO.EA-078-140822

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.

FEATURES

(For other voltages, please refer to MARK INFORMATIONS.)

• Output Voltage Accuracy........................................... ±2.0%(VR) for A/B type,

±2.0% (Reference Voltage for adjustable VR) for C type

• Dropout Voltage ........................................................ Typ. 0.2V (I^OUT=100mA) (VR)

• Temperature-drift Coefficient of Output Voltage ...... ±100ppm/°C

•

Absolute Maximum Voltage ..................................... 9.0V

Packages ................................................................. SOT-89-5, HSON-6 (Discontinued)

• Built-in Current Limit Circuit

• Internal Phase Compensation (small output capacitance such as 0.1µF Ceramic can be used with.)

APPLICATIONS

• Power source for CD-drives and DVD-drives, HDD.

• Local Power source for Notebook PC.
