DIO8016

The DIO8016 is a PMIC with 4 integrated LDOs. The PMIC has two low dropout LDOs for high current DVDD and two high PSRR LDOs for noise-sensitive power rails. The DIO8016 has two independent input pins for individual LDOs. The VIN1 pin is the power supply of LDO1 and LDO2; the VIN2 pin is the power supply of LDO3 and LDO4. VIN2 also supplies the LDO control module and digital logic module of the IC. The output voltage and power-up sequence of LDOs can be set through the I2C interface. The 7-bit I2C address of the device is 010 1000 by default. The DIO8016 is available in Pb-free, halogen-free, DFN2*2-10 package.
