Notes
1. Applies to both outputs.
2. Maximum combined output power is 12 watts. A maximum of 90% is avail-
able from either output.
3. 20% to 80% load on the positive output and 80% to 20% on the negative
output. See Figure 8.
4. 50% load on the positive output and 50% to 20% load on the negative output.
50% load on the negative output and 50% to 20% load on the positive output.
See Figure 7.
5. Indefinite short circuit protection not guaranteed above 125°C case temper-
ature.
