Note 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 represent pulse test
conditions with junction temperatures as indicated at the initiation of test.
Note 3. Recommended minimum load capacitance of 0.01µF to limit high frequency noise band-
width.
Note 4. The temperature coefficient of VOUT is typically within ±0.01% VO/°C.
