RT5133A Datasheet | Richtek

Description The RT5133A is a highly-integrated power management IC, which includes 8 LDOs for camera sensor applications, including 2-Ch DVDD, 4-Ch AVDD, 1-Ch VIO, 1-Ch VAF and 3 GPOs for portable devices. The output voltages, soft-start time and protections of regulators can be controlled by writing the registers through I2C. The LDO1 can be used to supply power to IO (VIO). The LDO2 can be used to supply power to auto focus unit (VAF). The LDO3 to LDO6 can be used to supply power to AVDD. The LDO7 and LDO8 can be used to supply power to DVDD. 3 GPO output pins can control external device or be reused for another purpose. The RT5133A is available in a WL-CSP-25B 1.84x1.84 (BSC) package.
