Electrical Characteristics
Limits in standard typeface are for TJ = 25ËC, and limits in boldface type apply over the temperature range of -40ËC to 125ËC.
Limits are guaranteed through design, testing, or correlation. The limits are used to calculate Nationalâs Average Outgoing
Quality Level (AOQL). Unless otherwise specified: VIN = 3.0V, VOUT = 1V, IL = 1 mA, COUT = 10 µF, CIN = 4.7 µF, VS/D = 2V,
CBYPASS = 10 nF.
