The

● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at IIN = 5mA, TA = 25°C. (Note 2)

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 (VEE) unless otherwise speciﬁed.

Note 3: An internal shunt regulator limits the VIN 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.
