Notes
1. Tc = –55°C to +125°C.
2. Up to 90% of the total output current/power is available from either output
providing the positive output is carrying at least 10% of the total output
power.
6. Indefinite short circuit protection not guaranteed above 125°C case.
7. Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
8. Transition time ≥ 10 µs.
3. Operation is limited below 17 V (see Figure 19).
4. Effect on the negative output under the following conditions:
+P 20% to 80%; –P 80% to 20%
9. 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.
