Note 1: Specifications are production tested at TA=25°C. Specifications over the -40°C to 85°C operating
temperature range are assured by design, characterization and correlation with Statistical Quality
Controls (SQC).
Note 2: The dropout voltage is defined as V_IN – V_OUT when V_OUT is 1% below the value of V_OUT for
V_IN = V_OUT + 0.5V. (Only applicable for V_OUT = 2.5V ~ 5V)
