(Refer to the test circuits, 0 < TJ < +125°C, IO=350mA, VI=10V, unless otherwis e specified, CI = 0.33µF, CO=0.1µF)
Notes:
*Load and line regulation are specified at constant junction temperature. Change in V
o
due to heating effects must be taken
into account separately. Pulse testing with low duty is used.
