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
device GND (V
EE
) unless otherwise specified.
Note 3: An internal shunt regulator limits the V
IN
pin to a minimum of
10.65V. Driving this pin to voltages beyond 10.65V may damage the part.
The pin can be safely tied to higher voltages through a resistor that limits
the current below 50mA.
Note 4: An internal clamp limits the DRAIN pin to a minimum of 3.5V.
Driving this pin to voltages beyond the clamp may damage the part. The
pin can be safely tied to higher voltages through a resistor that limits the
current below 2mA.
Note 5: Guaranteed by design and not subject to test.
