Note - The device is not guaranteed to function outside its operating
rating. Stresses listed under Absolute Maximum Ratings may cause
permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions
outside those listed in the operational sections of the specification is
not implied. Exposure to any absolute maximum rating for extended
periods may affect device performance and reliability. Devices are
ESD sensitive. Handling precautions are recommended.
Moisture Classification Level 1 (MSL 1) per J-STD- 020
Note 1 – Range depends on internal regulator set to 3.6V or 5.5V, see
12VIN specification below.

Base DC Hysteresis
mV
Note 1 – The Base DC Hysteresis voltage is measured with a 1.25V external voltage source. The resulting value is determined by subtracting
Threshold Low from Threshold High, VTH-VTL while monitoring the FAULT# pin state. Base DC Hysteresis is measured with a 1.25V input. Actual DC
Hysteresis is derived from the equation: (VIN/VREF)(Base Hysteresis). For example, if VIN=2.5V and VREF=1.25V then Actual DC Hysteresis=
(2.5V/1.25V)(0.003V)=6mV.
