15 / 52 page  LM4040-N, LM4040Q-N www.ti.com SNOS633H – OCTOBER 2000 – REVISED APRIL 2013 4.1-V LM4040-N Electrical Characteristics VR Tolerance Grades 'C' and 'D'; Temperature Grade 'I' Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C. The grades C and D designate initial Reverse Breakdown Voltage tolerances of ±0.5% and ±1.0%, respectively.

(2) 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. (3) The boldface (over-temperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage Tolerance ±[( ΔVR/ΔT)(maxΔT)(VR)]. Where, ΔVR/ΔT is the VR temperature coefficient, maxΔT is the maximum difference in temperature from the reference point of 25°C to T MIN or TMAX, and VR is the reverse breakdown voltage. The total over- temperature 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: C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C E-grade: ±3.5% = ±2.0% ±150 ppm/°C × 100°C Therefore, as an example, the A-grade 2.5-V LM4040-N has an over-temperature Reverse Breakdown Voltage tolerance of ±2.5V × 0.75% = ±19 mV. (4) 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.
