Notes:
1. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 10 µF) be placed from the +VOUT to
the -VOUT pins.
2. Transient recovery is measured to within a 1% error band for a load step change of 25%.
3. Short circuit protection is provided by a “hiccup mode” circuit.
4. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA. The maximum control current to the on/off
pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off.
5. These units should not be operated with a load under 5% of full load. Operation at no-load will not damage the unit, but they may
not meet all specifications.
6. These units should not be operated over +85°C. Exceeding +85°C may damage the unit.
7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above for the
correct rating.
