ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T
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
reference purposes only. Unless otherwise indicated, VIN
C
Note 1: Voltages above 5.1V can be obtained by using an external voltage divider.
