Notes
1. Tc = –55°C to +125°C
2. Operation is limited below 17V (see Figure 19).
3. Indefinite short circuit protection not guaranteed above 125°C case.
4. Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
5. Transition time ≥10 µs.
6. Parameter shall be tested as part of device characterization and after design
and process changes. Thereafter, parameters shall be guaranteed to the
limits specified in the electrical Characteristics table.
