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 +125°C. 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: V_IN = 12V, V_OUT = 3.3V
