The ripple current rating, ESR, and operating temperature are the major considerations when selecting the input capacitor. It is recommended that tantalum capacitors have a mini- mum voltage rating of at least twice the working voltage, including the ac ripple. This is necessary to insure reli- ability with 3.3-V input voltage bus applications. Output Capacitors (optional) The ESR of the output bulk (non-ceramic) capacitance must be between 10 m Ω ≤ESR ≤200 mΩ. Electrolytic capacitors have poor ripple performance at frequen- cies greater than 400 kHz but excellent low frequency transient response. Above the ripple frequency, ceramic decoupling capacitors are recommended to improve the transient response and reduce any high frequency noise components apparent during higher current excursions. A maximum of 100 µF ceramic capacitance may be added to the output bus. Tantalum/ Ceramic Capacitors Tantalum capacitors are acceptable on the output bus. Tantalum, Os-con®, or ceramic capacitor types are rec- ommended for applications where ambient temperatures fall below 0 °C. Ceramic capacitors may be used instead of electrolytic types on both the input and output bus. The input bus must have at least the minimum amount of capacitance. For the output bus the total amount of ceramic capacitance should be limited to 100 µF. Capacitor Tables Table 2-1 identifies vendors with acceptable ESR and maximum allowable ripple current (rms) ratings. Capaci- tors recommended for the output are identified under the Output Bus column with the required quantity. This is not an extensive capacitor list. Capacitors from other vendors are available with comparable specifications. Those listed are for guidance. The RMS ripple current rating and ESR (at 100 kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life.
