Electrical Characteristics (LM7806)

(Refer to the test circuits.

40qC TJ 125qC, IO = 500mA, VI = 11V, CI = 0.33PF, CO = 0.1PF, unless otherwise specified)

Note 4: 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.

Note 5: These parameters, although guaranteed, are not 100% tested in production.
