The maximum input voltage that can be applied to the LM25116MHX is 42V, but it's recommended to keep it below 40V for reliable operation.
To ensure the LM25116MHX operates within its thermal limits, make sure to provide adequate heat sinking, keep the ambient temperature below 85°C, and avoid high power dissipation during operation.
Yes, the LM25116MHX is qualified for automotive and high-reliability applications, but you should consult the Texas Instruments website for specific documentation and qualification information.
To minimize EMI and noise issues, follow good PCB layout practices such as separating analog and digital grounds, using a solid ground plane, and keeping sensitive nodes away from noisy components.
The recommended input capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor such as X5R or X7R type.
