Connection of NC pins in the MCP1703 LDO regulator
« on: October 06, 2014, 10:49:54 am »
I want to use the MCP1703 in the DFN-8 package and i'm wondering if i can connect the six NC pins to ground for better thermal performance and routing. The datasheet doesn't says nothing about this pins.

Hi exapod,

The six NC pins can be connected to the thermal pad (EP pin 9) to make a larger dissipation area and better thermal transfer of heat. This pad also needs to be connected to Vss (Ground) as stated on page 11 of the data sheet.
