Electrical Characteristics Limits in standard type are for T
J = 25°C only; limits in boldface type apply over the
junction temperature (T
J) range of -55°C to +125°C. Minimum and Maximum limits are guaranteed 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: V
IN = 12V, Vout = 1.8V
