External Capacitors

The LM8805 can stable work with cheap MLCC output Capacitor.

The LM8805 having high ripple rejection ratios, the series can be used with power supply noise. A 470pF

capacitor from the Bypass input to ground reduces noise present on the internal reference, which in turn

significantly reduces output noise. If output noise is not a concern, this input may be left unconnected. Larger

capacitor values Cbp be used, but results in a longer time period to rated output voltage when power is initially

applied.
