6.5 Electrical Characteristics

Specifications with standard type are for T_J = 25°C unless otherwise specified. 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 = 18 V, V_OUT = 3.3 V.
