to the device may occur. Electrical specifications do not apply when
operating the device beyond its specified Operating Ratings.
Electrical Characteristics
Limits in standard typeface are for TJ = 25°C and limits in boldface apply over the junction temperature range of –40°C to +125°C. Un-
less otherwise specified, VIN = VOUT + 1V, IL = 1mA, CL = 3.3µF, and VENABLE ≥ 2.0V
