WL2868C-20/TR

The WL2868C is PMIC with 7 integrated LDOs, the PMIC has 2 low dropout LDOs for high current DVDD and 5 high PSRR LDOs for noise sensitive power rails. The LDOs’ output voltage and power up sequence can be set through the I2C interface. WL2868C also integrated the fault monitoring features with interrupt indication. The 7bit I2C address of the device is default to 0101 111 but can be reprogramed so as multiple devices can be connected to the same I2C bus. WL2868C is available in 1.54×1.87 mm² 20 ball WCSP package. The device is Pb-free and halogen-free.
