8.2.1.9 Capacitors

TPS7H1101A-SP requires the use of a combination of tantalum and ceramic capacitors to achieve good volume to capacitance ratio. Table 8-2 highlights some of the capacitors used in the device. TI recommends to follow proper derating guidelines as recommended by the capacitor manufacturer based upon output voltage and operating temperature.

Note that polymer-based tantalum capacitors must be derated to at least 60% of rated voltage, whereas manganese oxide (MnO2) based tantalum capacitors should be derated to 33% of rated voltage depending upon the operating temperature.

TI recommends to use a tantalum capacitor along with a 0.1-µF ceramic capacitor. The device is stable for input and output tantalum capacitor values of 10 µF to 220 µF with the ESR range of 10 mΩ to 2 Ω. However, the dynamic performance of the device varies based on load conditions and the capacitor values used.

TI recommends a minimum output capacitor of 22 µF with ESR of 1 Ω or less to prevent oscillations. X7R dielectrics are preferred. See Table 8-2 for various capacitor recommendations.
