ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Ambient Temperature of T A = 25°C only; limits applying over the full
Operating Temperature range (-40°C to +85°C) 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 = V OUT + 1.5V, T A = 25°C, C IN = C OUT =10μF,
I OUT =10mA.
