The recommended PCB layout for the MAX4481AXT+T involves keeping the input and output tracks separate, using a solid ground plane, and placing a 10nF decoupling capacitor between VIN and GND. Additionally, it's recommended to place the device as close as possible to the load and use a short, direct connection to the output capacitor.
The output voltage tolerance for the MAX4481AXT+T can be calculated using the formula: Output Voltage Tolerance = (Output Voltage Nominal x Temperature Coefficient) + (Output Voltage Nominal x Line Regulation). Refer to the datasheet for the specific values of Temperature Coefficient and Line Regulation.
The maximum capacitive load that the MAX4481AXT+T can drive is 10μF. However, it's recommended to use a smaller output capacitor (e.g., 1μF to 4.7μF) to ensure stability and optimal performance.
The MAX4481AXT+T has built-in thermal shutdown and overcurrent protection features. When the device exceeds the junction temperature (typically 150°C) or the current limit (typically 1.5A), it will shut down or limit the output current to prevent damage. Ensure your design takes these features into account and provides adequate thermal dissipation and current limiting.
The recommended input capacitor value for the MAX4481AXT+T is 1μF to 10μF, with a recommended type of X5R or X7R ceramic capacitor. This capacitor helps to filter input noise and ensure stable operation.
