7 / 59 page LM25066I, LM25066IA www.ti.com SNVS824C – JUNE 2012 – REVISED MARCH 2013 Electrical Characteristics (continued) Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +85°C unless otherwise stated. Minimum and Maximum limits 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 = 12V.
