(3) Load and line regulation are measured at constant junction room temperature.
(4) The dropout voltage is the input/output differential at which the circuit ceases to regulate against further reduction in input voltage. It is
measured when the output voltage has dropped 100mV from the nominal value obtained at V

(7) Thermal Performance for the WSON was obtained using JESD51-7 board with six vias and an ambient temperature of 22°C. For
information about improved thermal performance and power dissipation for the WSON, refer to Application Note AN-1187 (SNOA401).
