JAJSEJ4C January 2018 – July 2018 TPSM84209
PRODUCTION DATA.
The minimum amount of required output capacitance for the TPSM84209 varies depending on the output voltage and whether or not a feed-forward capacitor, CFF, is used (see Feed-Forward Capacitor for more information on CFF). Table 4 lists the minimum output capacitance for several output voltage ranges when not using CFF. The required output capacitance must be comprised of all ceramic capacitors or a combination of ceramic and polymer-type capacitors. The effects of temperature and capacitor voltage rating must be considered when selecting capacitors to meet the minimum required capacitance.
When adding additional output capacitance, ceramic capacitors or a combination of ceramic and polymer-type capacitors can be used. The required capacitance above the minimum is determined by actual transient deviation requirements. See Table 5 for a preferred list of output capacitors by vendor.
