7.2.1.1.1 Recommended Capacitors for the Legacy Chip

Most tantalum or aluminum electrolytics can be used at the input. Film-type capacitors also work but at higher cost. Ceramic capacitors can be used at the output, but the low ESR (as low as 5mΩ to 10mΩ) can make the output not meet the minimum ESR requirement. If a ceramic capacitor is used, a series resistor between 0.1Ω to 2Ω must be added to meet the minimum ESR requirement.
