*2: Thermal protection circuits may operate if the junction temperature exceeds 135
°C
sRecommended Operating Conditions
*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.
