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 T_J = 25°C and limits in boldface apply over the junction temperature range of –40°C to +125°C. Un-
less otherwise specified, V_IN = V_OUT + 1V, I_L = 1mA, C_L = 3.3µF, and V_ENABLE ≥ 2.0V
