(VI = 10V, IO = 40mA, 0
°C ≤ TJ ≤ 125°C, CI = 0.33µF, CO = 0.1µF, unless otherwise specified. (Note 1)
Note:
1. The maximum steady state usable output current and input voltage are very dependent on the heat sinking and/or lead length
of the package. The data above represent pulse test conditions with junction temperature as indicated at the initiation of tests.
2. Power dissipation PD
≤ 0.75W.
