A good PCB layout for the MAX5380MEUK+T involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated analog layer to minimize noise.
The MAX5380MEUK+T requires a single 2.7V to 5.5V power supply. It's recommended to power the device with a low-noise, low-dropout regulator. The power sequencing requirement is to power up the device after the input voltage has reached its nominal value, and to power down the device before the input voltage drops below its minimum specified value.
The recommended input capacitance is 1uF to 10uF, and the recommended output capacitance is 1uF to 22uF. The capacitance values depend on the specific application and the desired level of filtering and noise reduction.
The MAX5380MEUK+T output voltage range can be configured by connecting the VOUT pin to the desired output voltage through a resistive divider network. The output voltage range can be adjusted from 0.9V to 5.5V by changing the resistive divider ratio.
The MAX5380MEUK+T has a thermal pad on the bottom of the package, which should be connected to a solid ground plane on the PCB to dissipate heat. Additionally, it's recommended to use thermal vias and a heat sink if the device is expected to operate at high temperatures or high currents.
