Note:
*1) Measured using a double sided board with 1”x2” square inches of copper area connected to the GND pins for “heat spreading”.
*2) EN pin input voltage must be always less than or equal to input voltage.
*3) It is for the EC49513L only.
*4) EN Pin with internal pull high resistor is about several hundreds of KΩ for EC49513A only.
