300mA LDO REGULATOR

NO. EA-078-0305

R1130xxxxA/B/C SERIES

OUTLINE

The R1130xxxxx Series are CMOS-based voltage regulator (VR) ICs. VR function has features of high ripple rejec-

tion, 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 R1130xxxxx 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 R1130xxxxx 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-6P, high density mounting of the ICs on

boards is possible.
