Notes:
2. 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 represents pulse test conditions with junction temperature as
indicated at the initiation of tests.
3. Power dissipation P D ≤ 0.75 W.
4. These parameters, although guaranteed over the recommended operating conditions, are not 100% tested in
production.
5. Recommend minimum load capacitance of 0.01 μ F to limit high-frequency noise.
