300mA LDO REGULATOR R1130XxxxA/B/C Series

■ OUTLINE

The R1130Xxxxx Series are voltage regulator (VR) ICs by CMOS process. 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.

Output Voltage of the R1130xxxxC type is adjustable with external resistors.

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 package for these ICs is the SOT-89-5 package or HSON-6P, high density mounting of the ICs on

boards is possible.
