5 / 28 page LM26001, LM26001Q www.ti.com SNVS430F – MAY 2006 – REVISED NOVEMBER 2010 Electrical Characteristics (continued) Specifications in standard type are for TJ = 25°C only, and limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C. Unless otherwise stated, Vin=12V. Minimum and Maximum limits are guaranteed 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.
