Although an input capacitor is not required for stability, good analog design practice is to connect a capacitor from IN to GND. This capacitor counteracts reactive input sources and improves transient response, input ripple, and PSRR. Use an input capacitor if the source impedance is more than 0.5Ω. For typical operation of the TLV773, connect a 1μF capacitor to the input. Use a higher value capacitor if large, fast rise-time, load, or line transients are anticipated. Additionally, use a higher-value capacitor if the device is located several inches from the input power source.

Dynamic performance of the device is improved by using an output capacitor. Use an output capacitor within the range specified in the Recommended Operating Conditions table for stability. Make sure that the minimum derated output capacitance is equal to or greater than 0.47μF. When the output voltage is ramping up, the inrush current depends on the size of the output capacitance. During start-up, the output current is potentially as high as the current limit value for larger output capacitors.
