ELECTRICAL CHARACTERISTICS
(V
to +85°C, unless otherwise noted.) (Note 3)
Note 1: Output current and on-resistance are specified at 3.6V input voltage. The IC operates to 2.7V with reduced performance.
Note 2: The specified maximum negative output voltage is referred to V
Note 3: Specifications to -40°C are guaranteed by design, not production tested.
