(1) Low duty cycle testing is used to maintain the junction temperature as close to the ambient temperature as possible. Changes in output
voltage due to thermal effects are covered separately by the thermal regulation specification.
(2) Dropout is defined as the input to output differential at which the output drops 2% below its nominal value measured at 1-V differential.
(3) For stability across the input voltage and temperature. For ADJ versions, the minimum current can be set by R1 and R2.
(4) Thermal regulation is defined as the change in output voltage at a specified time after a change in power dissipation is applied,
excluding line and load regulation effects.
(5) C_BYP is optional and connected to the BYP/ADJ pin.
