NOTES:

(1) Low duty cycle pulse testing with Kelvin connections required.

(2) Defined as the input to output differential at which the output voltage drops 100mV below the value measured

at a differential of 1V. Not measurable on 1.5V and 1.8V parts due to minimum VIN constraints.

(3) Guaranteed by design.
