What capacitor values are recommended for SET mitigation?
It is advisable to use tantalum input and output capacitors with a minimum of 1 uF, along with decoupling polyester capacitors.
How can short-duration SET pulses be minimized?
Short-duration pulses depend on ESL and stray inductances; they cannot be suppressed by increasing capacitance but require board-level actions like low ESR capacitors.
