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