Package
Typical Application
* Required if regulator is located more than 2″ from power supply filter capacitor.
** Required for stability. See Electrical Characteristics for required values. Must be rated over intended operating
temperature range. Effective series resistance (ESR) is critical, see curve. Locate capacitor as close as possible to
the regulator output and ground pins. Capacitance may be increased without bound.
