Notes:

Low duty cycle pulse testing with Kelvin connections required.

Defined as the input to output differential at which the output voltage drops to .5% below the value measured at a differential of 0.8V.

Required to maintain regulation. Voltage set resistors R and R2 are usually utilized to meet this requirement. Adjustable versions only.

Guaranteed by design.
