8.1.2 Input and Output Capacitor Requirements

A minimum 2.2-µF ceramic capacitor at the input is required for stability, A minimum 2.2-µF ceramic capacitor with a maximum ESR value of less than 250 mΩ at the output is also required for stability. The input capacitor counteracts reactive input sources and improves transient response, input ripple, and PSRR. A higher-value input capacitor may be necessary if large, fast rise-time load or line transients are anticipated, or if the device is located several inches from the input power source. Dynamic performance of the device is improved with the use of an output capacitor larger than the minimum value specified in the Recommended Operating Conditions table.

Although a bias capacitor is not required, connect a 0.1-µF ceramic capacitor from BIAS to GND for best analog design practice. This capacitor counteracts reactive bias sources if the source impedance is not sufficiently low.

Place the input, output, and bias capacitors as close as possible to the device to minimize traces parasitics.
