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 VIN – VOUT when VOUT is 1% below the value of VOUT for

VIN = VOUT + 0.5V. (Only applicable for VOUT = 2.5V ~ 5V)
