Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltages with respect to the ground pin, unless otherwise noted.
The absolute maximum rating is VINN – 0.3 V or –3 V, whichever is greater.
The absolute maximum rating is VINN – 0.3 V or –33 V, whichever is greater.
The absolute maximum rating is VINP + 0.3 V or 33 V, whichever is smaller.
The absolute maximum rating is VINP + 0.3 V or 36 V, whichever is smaller.
The absolute maximum rating is VINP + 0.3 V or 3 V, whichever is smaller.
The absolute maximum rating is VINP + 0.3 V or 2 V, whichever is smaller.

VALUE UNIT
VESD Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±500
JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

CFFP Positive channel feed-forward capacitor; connect from VOUTP to FBP 0 10 100 nF
CFFN Negative channel feed-forward capacitor; connect from VOUTN to FBN 0 10 100 nF
R2P Lower positive feedback resistor 10 240
R2N Lower negative feedback resistor (from FBN to BUF) 10 240
TJ Operating junction temperature –40 125 °C
The nominal input and output capacitor value of 10-µF accounts for the derating factors that apply to X5R and X7R ceramic capacitors. The assumed overall derating is 80%.
Minimum load required when feedback resistors are not used. If feedback resistors are used, keeping R2x below 240 kΩ satisfies this requirement.
For startup tracking to function correctly a minimum 4.7-nF CNR/SS capacitor must be used.
