8.2.2.4 VTTSNS Connection
To achieve tight regulation with minimum effect of trace resistance, a remote sensing pin (VTTSNS) should be connected to the positive pin of the VTT pin output capacitor or capacitors as a separate trace from the high-current path from VTT. Consider adding a low-pass R-C filter at the VTTSNS pin in case the ESR of the VTT output capacitor or capacitors is larger than 2 mΩ. The R-C filter time constant should be approximately the same or slightly lower than the time constant of the VTT output capacitance and ESR.
