3 / 24 page © 2006 Fairchild Semiconductor Corporation www.fairchildsemi.com LM78XX / LM78XXA Rev. 1.3.0 3 Electrical Characteristics (LM7805) Refer to the test circuit, -40°C < TJ < 125°C, IO = 500 mA, VI = 10 V, CI = 0.1 μF, unless otherwise specified. Notes: 2. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty is used. 3. These parameters, although guaranteed, are not 100% tested in production. Symbol Parameter Conditions Min. Typ. Max.
