All room temperature limits are 100% production tested or specified through statistical analysis. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). (2) Typical numbers are at 25°C and represent the most likely norm. (3) Feedback current flows into the pin. 4 Submit Documentation Feedback Copyright © 2002–2013, Texas Instruments Incorporated Product Folder Links: LM2705 |
