Note 1: Specifications to -40°C are guaranteed by design and not production tested.
Note 2: Guaranteed by line-regulation test.
Note 3: Adjustable mode only.
Note 4: The dropout voltage is defined as V

2V. Since the
minimum input voltage is 2.5V, this is applicable only for voltages of 2.5V or higher.
Note 5: The FAULT detection voltage is the difference from input to output voltage. Maintain the input above this level to ensure
good line and load regulation.
