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.
The R1130x Series are CMOS-based voltage regulator (VR) ICs designed for high ripple rejection, low dropout voltage, high output voltage accuracy, and ultra-low supply current. The series includes fixed output voltage types (A/B) and adjustable output voltage types (C). These regulators are suitable for powering CD-drives, DVD-drives, and HDDs, as well as serving as local power sources for Notebook PCs.
The ICs are available in SOT-89-5 and HSON-6 packages, allowing for high-density mounting. Key features include a built-in current limit circuit, internal phase compensation allowing the use of small output capacitances like 0.1uF ceramic capacitors, and a chip enable circuit for the A and B types. The maximum output current is 300mA.
