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

Applications Information.
