*1: VIN (max) and IO (max) are restricted by the relationship PD = (VIN - VO) × IO.
Calculate these values referring to the reference data.
*2: Refer to the dropout voltage section.
*3: For the SI-3012LU, set the input voltage to at least 2.4 V, and secure the minimum voltage as explained in Setting DC Input Voltage,
