The grades C and D designate initial Reference Voltage Tolerances of ±0.5% and ±1%, respectively for VOUT = 5V.

This is caused by the series resistance of the die attach between the die (-) output and the package (-) output pin. See the Output Saturation (SOT-23 only) curve in the Typical Performance Characteristics section. (2) Typicals are at TJ = 25°C and represent most likely parametric norm. (3) Limits are 100% production tested at 25°C. Limits over temperature are ensured through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate AOQL. (4) Reference voltage and temperature coefficient will change with output voltage. See Typical Performance Characteristics curves. (5) Load regulation is measured on pulse basis from no load to the specified load current. Ouput changes due to die temperature change must be taken into account separately.- (6) When VOUT ≤ 1.6V, the LM4041-N ADJ in the SOT-23 package must operate at reduced IR. This is caused by the series resistance of the die attach between the die (-) output and the package (-) output pin. See the Output Saturation (SOT-23 only) curve in the Typical Performance Characteristics section. (7) Thermal hysteresis is defined as the difference in voltage measured at +25°C after cycling to temperature -40°C and the 25°C measurement after cycling to temperature +125°C.
