Electrical Characteristics (MC78M08) (Continued)
(Refer to the test circuits, 0 < TJ < +125
°C, IO=350mA, VI=14V, unless otherwise specified, CI = 0.33F, CO=0.1F)
Note:
1. Load and line regulation are specified at constant junction temperature. Change in VO due to heating effects must be taken
into account separately. Pulse testing with low duty is used.
