Note 2: Tantalum, electrolytic or low cost ceramic capacitors may be used.
Note 3: Regulation voltages and dropout resistance is measured at constant junction temperature using low duty cycle pulse testing.
Note 4: Line regulation is displayed as the average regulation across the full operating range measured in %/V.
