Theoutput current capability of the Regulator is in excess of800 mA, with a typical dropout Voltage of less than protective features include current and thermallimiting.* The MC33269 requires an external output capacitor forstability. The capacitor should be at least 10 mF with anequivalent series resistance (ESR) of less than 10 W butgreater than W over the anticipated operatingtemperature range.
