ELECTRICAL CHARACTERISTICS

Unless specified: VEN = VIN

Adjustable Option (VADJ > VTH(ADJ)): VIN = 2.2 to 5.5V and IO = 10µA to 1.5A

Fixed Options (VADJ = GND): VIN = (VO + 0.7V) to 5.5V and IO = 0A to 1.5A

Values in bold apply over the full operating temperature range.

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 VADJ exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from the

error amplifier and connects VADJ instead.
