SNVS724C – JUNE 2011 – REVISED MAY 2013

ELECTRICAL CHARACTERISTICS (continued)

Specification with standard type are for TA = TJ = +25°C only; limits in boldface type apply over the full Operating Junction

Temperature (TJ) range. Minimum and Maximum are specified through test, design or statistical correlation. Typical values

represent the most likely parametric norm at TJ = +25°C, and are provided for reference purposes only. Unless otherwise

stated the following conditions apply: VIN = 5V and VOUT – VIN = 3V.
