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 to 1% below the value measured at a differential of 0.95V for 2.2V ≤ V_OUT ≤ 4.55V
at adjustable mode configuration. Not measurable on outputs less than 2.2V due to minimum V_IN constraints. See typical characteristics curves.
(3) Defined as the output current at which the output voltage drops to 2% below the value measured at output current of 10mA.
(4) Guaranteed by design.
(5) When V_ADJ exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the error amplifier and connects V_ADJ instead.
