A recommended PCB layout for optimal thermal performance would be to have a large copper area on the bottom layer connected to the thermal pad, and to use thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended.
To ensure the stability of the output voltage, it is recommended to use a capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. A 10uF to 22uF capacitor with an ESR of less than 100mΩ is recommended.
The maximum input voltage that can be applied to the LTR18EZPF2401 is 28V. Exceeding this voltage may cause damage to the device.
To protect the device from overcurrent, it is recommended to add an overcurrent protection circuit, such as a fuse or a current sense resistor, in series with the input voltage.
A 1uF to 10uF ceramic capacitor with an X7R or X5R dielectric is recommended for the input capacitor. This helps to filter out noise and ripple on the input voltage.
