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.
3. These parameters although guaranteed over the recommended operating conditions are not 100% tested in production.
4. Recommend minimum load capacitance of 0.01uF to limit high frequency noise.
5. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply
when operating the device outside of its stated operating conditions.
* CI is required if regulator is located an appreciable distance from power supply filter.
** Co is not needed for stability; however, it does improve transient response.
