Notes
1. The sum of the 12 volt auxiliary output currents may not exceed 625 mA.
The sum of the 15 volt auxiliary output currents may not exceed 500 mA.
2. The sum of the auxiliary output power may not exceed 7.5 watts.
3. Case temperature –55°C to +125°C.
4. Load regulation for the +5 is specified at 0.0 to 1.5 A with the aux. both held
at 3.76 W (313 mA for the ±12, 250 mA for the ±15). Load regulation for the
aux. is specified as both aux. from 0.0 to 3.76 W (313 mA for ±12, 250 mA
for ±15) at the same time with the +5 held at 1.5 A.
5. Cross regulation only occurs between the two auxiliaries and is measured on
–aux. +5 is held constant at 1.0 A. Cross regulation is specified for two
conditions:
Negative aux.= 3.76 W; positive aux.= 0.37 W to 3.76 W.
Negative aux. = 0.37 W to 3.76 W; positive aux. = 3.76 W.
6. Load fault = <0.05 Ω.
7. Transition time is 2 – 10 µs.
8. Time to settle to within 1% of Vout final value.
