2.5-V LM4040-N Electrical Characteristics

VR Tolerance Grades 'A' and 'B'; Temperature Grade 'I' (AEC Grade 3)

Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C. The grades A and B designate initial

Reverse Breakdown Voltage tolerances of ±0.1% and ±0.2%, respectively.

(1)

Typicals are at TJ = 25°C and represent most likely parametric norm.

(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.
