Electrical Characteristics (continued)
Unless otherwise stated the following conditions apply: VIN = 14V, EN =2.00V, UVLO =2.00V, OVP = 1.50V, and T
J
= 25°C.
Limits in standard type are for T
J
= 25°C only; limits in boldface type apply over the operating junction temperature (T
J
)
range of -40°C to +125°C. Minimum and Maximum limits are ensured through test, design, or statistical correlation. Typical
values represent the most likely parametric norm at T
J
= 25°C, and are provided for reference purposes only.
