ELECTRICAL CHARACTERISTICS (continued)
(V+ = VL = 5.2V or V+ = 5.5V to 23V, EN_ = VL, SYNC = GND, I
R
Note 1: Specifications at -40°C are guaranteed by design and not production tested.
Note 2: Operating supply range (V+) is guaranteed by VL line regulation test. Connect V+ to VL for 5V operation.
Note 3: Output current may be limited by the power dissipation of the package, see the Power Dissipation section in the
