A good PCB layout for optimal thermal performance involves placing the device near a thermal pad or a heat sink, using a 2-layer or 4-layer board, and minimizing the distance between the device and the thermal pad or heat sink.
Ensure the input voltage is within the recommended range (4.5V to 18V), the output voltage is set correctly, and the device is operated within the recommended temperature range (-40°C to 125°C).
A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF is recommended for optimal performance.
The output voltage accuracy is ±2% and the tolerance is ±1.5%. Calculate the output voltage using the formula: Vout = (R1/R2) * (1.25V) ± (2% of Vout) ± (1.5% of Vout).
