A 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer is recommended. Ensure that the thermal pad is connected to the ground plane.
Use a soft-start circuit to limit the inrush current during start-up, and ensure that the input voltage rises slowly (e.g., 10-20 ms) to prevent high inrush currents. For shutdown, ensure that the input voltage falls slowly to prevent back-EMF.
The maximum allowed voltage on the BYPASS pin is 6.5V. Exceeding this voltage may damage the internal voltage regulator.
Use a low-ESR input capacitor, minimize the input voltage, and ensure that the device is in a low-power state during standby. Also, consider using a low-power mode or shutdown mode to reduce standby power consumption.
A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22 μF is recommended. The capacitor should be placed close to the VIN pin to minimize parasitic inductance.
