PRODUCTION DATA
The high impedance of the FB pin makes the regulator sensitive to parasitic capacitances that can couple undesirable signals from nearby components (especially from logic and digital devices, such as microcontrollers and microprocessors); these capacitively-coupled signals can produce undesirable output voltage transients. In these cases, use a fixed-voltage version of the TPS7A16-Q1, or isolate the FB node by flooding the local PCB area with ground-plane copper to minimize any undesirable signal coupling.
