Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. Adjustable devices tested at VREF; external resistor tolerance is not taken into account.
2. Dropout is defined as the voltage from the input to VOUT when VOUT is 3% below nominal.
3. 3.25 V is a test condition of this device and can be adjusted by referring to Figure 8.
