The TPS742 family does not require any output capacitor for stability. If an output capacitor is needed, the device is designed to be stable for all available types and values of output capacitance. The device is also stable with multiple capacitors in parallel, which can be of any type or value.

The capacitance required on the IN and BIAS pins is strongly dependent on the input supply source impedance. To counteract any inductance in the input, the minimum recommended capacitor for V_IN and V_BIAS is 1μF. If V_IN and V_BIAS are connected to the same supply, the recommended minimum capacitor for V_BIAS is 4.7 μF. Use good quality, low ESR capacitors on the input; ceramic X5R and X7R capacitors are preferred. Place these capacitors as close to the pins as possible for optimum performance.
