the Typical Performance Characteristics section.

Note 6: Determined by design, not tested in production.

Note 8: When floating, the ACC pin can tolerate ±5µA of leakage.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: All currents into pins are positive; all voltages are referenced to

GND unless otherwise specified.

Note 3: Pulsed less than 5µs.

Note 4: The connection circuitry always regulates the output to a higher
