All limits at TA = TJ = 25°C are 100% production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control methods. (2) All limits are specified at TA = TJ = 25°C only (standard typeface) or over the entire operating temperature range of the indicated device (boldface type). All limits are 100% production tested and are used to calculate Outgoing Quality Levels. (3) Output current will decrease with increasing temperature but will not drop below 1A at the maximum specified temperature. 4 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LM2940-N LM2940C |
