POWER MANAGEMENT
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 0.7V.
(3) Required to maintain regulation. Voltage set resistors R1 and R2 are usually utilized to meet this
requirement. Adjustable versions only.
(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.

Electrical Characteristics (Cont.)
Unless specified: V
EN = VIN. Adjustable Option (VADJ > VTH(ADJ)): VIN = 2.2V to 5.5V and IO = 10µA to 3A.
Fixed Options (V
ADJ = GND): VIN = (VO + 0.7V) to 5.5V and IO = 0A to 3A. Values in bold apply over the full operating temperature range.
