Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its rated operating conditions.
Note 3: During current limit, thermal limit, or electronic shutdown the input current will increase if the input to output differential voltage exceeds 8V. See Overvoltage
Protection in Application Hints.
Note 4: The LM6125 series buffers contain current limit and thermal shutdown to protect against fault conditions.
