A good PCB layout for the ADP5130 involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. Additionally, it's recommended to use a separate power plane for the input voltage and to keep the output voltage traces away from the input voltage traces to prevent noise coupling.
The choice of input and output capacitors for the ADP5130 depends on the specific application requirements. In general, low-ESR ceramic capacitors with a capacitance value of 1-10uF are recommended for the input and output. The capacitor selection should also consider the voltage rating, ripple current rating, and temperature range of the application.
The ADP5130 can handle an input voltage up to 18V, but it's recommended to operate the device within the specified input voltage range of 4.5V to 15V for optimal performance and reliability.
The ADP5130 is rated for operation up to 85°C, but it's recommended to derate the output current and input voltage according to the temperature derating curve provided in the datasheet to ensure reliable operation in high-temperature environments.
To ensure stability, it's recommended to follow the recommended PCB layout and component selection guidelines, and to add a 10nF to 100nF capacitor between the VIN and GND pins to filter out high-frequency noise. Additionally, the output voltage should be decoupled with a capacitor to prevent oscillation.
