TPS7A0533 and REF3533 are used in this design to power the devices on the board. For TPS7A0533, the device accepts up to 5.5V input voltage and generates a 3.3V rail for TMAG6180, TLV9062, MSPM0G3507 and THVD1454 supply. Two parallel capacitors C5 (1μF) are used for noise decoupling, an output capacitor C6(10μF) is used for minimize the output voltage ripple.
For REF3533, the device is powered by an external 5V supply and generates precise 3.3V output as MSPM0 ADC’s reference. Similarly with the TPS7A0533, C8 (100nF) is used for decoupling. C9(1uF) is used for minimize the output voltage ripple.
