... Note 2: During current limit or thermal limit, the input current will increase if the input to output differential voltage exceeds 8V. For input to output differential voltages in excess of 8V the input current should be limited to Note 3: The LM6121 series buffers contain current limit and thermal shutdown to protect against fault conditions. Note 4: The thermal resistance θ ...
