1. Those parameters are achieved by characterization on a small sample size from typical devices under typical conditions.

2. Up to 100 mA as pulsed current.

3. Measured output current when the output voltage has dropped 200 mV from its nominal value obtained at Vs = 10.5 V and

Io = 25 mA.

4. Guaranteed by design.

5. Thermal protection is guaranteed by design and characterization.
