*1: V
*2: Refer to the Dropout Voltage parameter. (Refer to Setting DC Input Voltage on page 9.)
*3: I
*4: Output is ON even when output control terminal V
*5: These products cannot be used in the following applications because the built-in foldback-type overcurrent protection may cause errors during start-up stage.
