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. 7.11 Typical Characteristics Figure 1. µA7805 Bias Current vs Voltage Differential at 25°C 10 Submit Documentation Feedback Copyright © 1976–2015, Texas Instruments Incorporated Product Folder Links: uA7805 uA7808 uA7810 uA7812 uA7815 uA7824 |
