ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T J = 25°C only; limits applying over the full
Operating Junction Temperature range are denoted by a “?”. 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 indicated, V IN = 4.5V to 29V, C IN = 1μF, T J = –40°C to 125°C.
