Turn-On Time

Turn-Off Time

VIN = 4.5V

VIN = 3.0V

VSET required to turn the switch off (Note 1)

IOUT = 500mA, VOUT > 1.6V

ISINK = 1mA, VSET = 1.4V

VIN = 5V, IOUT = 500mA

VIN = 5V, IOUT = 500mA

Note 1: Tested with IOUT = 100mA and VSET raised until VIN - VOUT ≥ 0.8V.

Note 2: Specifications to -40°C are guaranteed by design, not production tested.
