Guaranteed by characterization test and/or analysis. Not a production test. 2. The specified max current is available from either output. 3. Up to 90% of the total output current/power is available from either output providing the opposite output is carrying at least 10% of the total output power. 4. Operation is limited below 16 V (see Figure 22 on page 10). 5. Effect on the negative output under the following conditions: +POUT 20% to 80%; –POUT 80% to 20%. 6. Effect on the negative output under the following conditions: +POUT 50%; –POUT 10% to 50%. See Figure 21 on page 10. 7. Tested with 6800 pF ceramic bypass capacitor connected externally from input common to case. 8. Indefinite short circuit protection not guaranteed above 125°C case temperature. 9. Recovery time is measured from application of the transient to point at which VOUT is within 1% of final value. 10. Tested on release from inhibit.
