Note 2: Regulation is measured at constant junction temperature, using pulsed on time. Note 3: Current limit is measured at constant junction temperature, using pulsed on time. Note 4: Dropout is measured at constant junction temperature, using pulsed on time, and the criterion is VOUT inside target value2%. Note 5: Dropout test is skipped at the condition of VIN<3V.

Any type of capacitor can be used, but not Aluminum electrolytic when operating below -20C. The capacitance may be increased without limit. Besides, another 1F capacitor (or larger) should be placed between VIN to GND.
