PRODUCTION DATA
For the output capacitor, it is recommended to use small ceramic capacitors placed as close as possible to the VOUT and PGND pins of the IC. The recommended nominal output capacitor value is a single 22 μF for the TPS63805/TPS63807 and 2x47 μF for the TPS63806 for all programmed output voltages ≤ 3.6 V. Above that voltage, 2x22 μF for the TPS63805/TPS63807 and 3x47 μF for the TPS63806 capacitors are recommended.
It is important that the effective capacitance is given according to the recommended value in Section 8.3. In general, consider DC bias effects resulting in less effective capacitance. The choice of the output capacitance is mainly a trade-off between size and transient behavior since higher capacitance reduces transient response overshoot and undershoot and increases transient response time. Table 10-4 lists possible output capacitors.
There is no upper limit for the output capacitance value.
