Typical Application
10011301
* Required if the regulator is located more than 3 inches from the power supply filter capacitors.
** Required for stability. C
must be at least 10 µF (over the full expected operating temperature range) and located as close as possible to the regulator. The
out
equivalent series resistance, ESR, of this capacitor may be as high as 3Ω.
