A thermal pad is recommended under the package to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are also recommended.
To ensure stable operation, use an output capacitor with an ESR of 10mΩ or less. Additionally, add a 1-2nF ceramic capacitor in parallel with the output capacitor to improve stability.
The maximum input voltage that can be applied to the device is 18V, but it is recommended to operate within the specified input voltage range of 7-15V for optimal performance.
The output voltage can be adjusted by changing the resistor divider ratio of R1 and R2. A higher ratio will result in a higher output voltage, and a lower ratio will result in a lower output voltage.
A minimum input capacitance of 1uF is recommended for stable operation, but a larger capacitance may be required depending on the input voltage and output current requirements.
