Thermal effects must be taken into account separately. All characteristics are measured with a 0.33- μF capacitor across the input and a 0.1-μF capacitor across the output. (2) This parameter is validated by design and verified during product characterization. It is not tested in production. 8 Submit Documentation Feedback Copyright © 1976–2015, Texas Instruments Incorporated Product Folder Links: uA7805 uA7808 uA7810 uA7812 uA7815 uA7824 |
