ELECTRICAL CHARACTERISTICS (continued)

Note 2: Continuous output current is tested with one output at a time.

Note 3: See the

Thermal Shutdown with Temperature Hysteresis section.

Note 4: A series resistor can extend load capacitance range. The settling time can be optimized by a small series resistance. See

the

Applications Information section for more information.

Note 5: Inputs are protected by back-to-back diodes.
