How to select the part number and feedback resistor value for 12 to 3.3V and 12 to 5V?
Hi Vivek,
In the datasheet, section 9.2.2.2 Choose Feedback Resistors details how to size the feedback resistors. When choosing part numbers, the considerations are size, cost, power rating, and tolerance, which are mostly dependent on your application requirements. To maintain the device's specified accuracy, use 1% or better resistors.
Regards,
Nick
