The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve output voltage regulation.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and avoid long traces between the input and output pins. Additionally, adding a small ceramic capacitor (e.g., 10nF) between the VOUT and GND pins can help to improve stability.
The maximum output current capability of the MAX860ISA is 1A, but it can be limited by the input voltage, output voltage, and thermal considerations. Be sure to check the datasheet for specific current limits and thermal derating factors.
The MAX860ISA is rated for operation up to 125°C, but its performance and reliability may be affected at high temperatures. Be sure to check the datasheet for thermal derating factors and consider using thermal management techniques, such as heat sinks or thermal interfaces, to ensure reliable operation.
The output voltage of the MAX860ISA can be adjusted by connecting a resistive divider network between the VOUT and ADJ pins. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
