NOTE:
*1: Unless otherwise stated, VIN=5.0V, CE=5.0V, MODE=5.0V, FB=0.9V
*2: The operation may not be stable at no load, if the step-down ratio (VOUT/VIN x 100) becomes lower than 12%.
*3: The regulator block is used only for bootstrap. Please do not use as a local power supply.
*4: Release voltage: (VDR) = VDF + HYS x VDF
