Note 1: All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
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.
