A thermal pad on the bottom of the package is recommended to be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
To ensure stability, a minimum output capacitance of 10uF with an ESR of 1ohm or less is recommended. Additionally, the output capacitor should be placed as close to the output pin as possible.
The maximum input voltage that can be applied to the device is 18V, but it is recommended to operate within 15V to ensure reliable operation.
The device has built-in overcurrent protection, but it is recommended to add an external fuse or PTC thermistor to protect the device from excessive current surges.
A 1uF to 10uF ceramic capacitor with an X5R or X7R dielectric is recommended to be placed as close to the input pin as possible to filter out noise and ripple.
