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.

The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage

Tolerance ±[(

tolerance for the different grades in the industrial temperature range where max

ΔT = 65°C is shown below:

A-grade: ±0.75% = ±0.1% ±100 ppm/°C × 65°C

B-grade: ±0.85% = ±0.2% ±100 ppm/°C × 65°C

C-grade: ±1.15% = ±0.5% ±100 ppm/°C × 65°C

D-grade: ±1.98% = ±1.0% ±150 ppm/°C × 65°C

E-grade: ±2.98% = ±2.0% ±150 ppm/°C × 65°C

The total over-temperature tolerance for the different grades in the extended temperature range where max

ΔT = 100 °C is shown

below:

B-grade: ±1.2% = ±0.2% ±100 ppm/°C × 100°C

C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C

D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C

E-grade: ±4.5% = ±2.0% ±150 ppm/°C × 100°C

Therefore, as an example, the A-grade LM4041-N 1.2 has an over-temperature Reverse Breakdown Voltage tolerance of ±1.2 V ×

0.75% = ±9.2 mV.

Load regulation is measured on pulse basis from no load to the specified load current. Output changes due to die temperature change

must be taken into account separately.

(5)

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.
