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 VCC, and not to GND. With VCC = 3.3V, the maximum negative
output is then -12.7V.
Note 3: Specifications to -40°C are guaranteed by design, not production tested.
