ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Temperature of T A = 25°C only; limits applying over the full
Operating 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 A = 25°C, and are provided for reference
purposes only. Unless otherwise indicated, V IN = 3.6V, C IN =10 μ F, C OUT =2.2 μ F, C FLY =0.22 μ F, T A = –40°C to 85°C.
