Electrical Characteristics (continued)
Limits in standard type are for T
J
= 25°C only; limits in boldface type apply over the junction temperature (T
J
) range of -40°C
to +85°C unless otherwise stated. Minimum and Maximum limits are specified 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. Unless
otherwise stated the following conditions apply: VIN = 12V. See
