8.2.1.2.5 Input Capacitor Selection

TI recommends low-ESR ceramic capacitors for good input voltage filtering. The TPS61087-Q1 has an analog input (IN). Therefore, TI recommends placing a 1-μF bypass capacitor as close as possible to the IC from IN to GND.

Two 10-μF (or one 22-μF) ceramic input capacitors are sufficient for most of the applications. For better input voltage filtering, this value can be increased. See Table 6 for output capacitor selection. Customers must verify and validate selected components for suitability with their application.
