Do not place any of the capacitors on the opposite side of the PCB from where the regulator is installed. TI strongly discourages using vias and long traces because of the negative impact on system performance. Vias and long traces can also cause instability.
Equivalent series inductance (ESL) and ESR must be minimized to maximize performance and ensure stability. Every capacitor must be placed as close to the device as possible and on the same side of the PCB as the regulator.
