13 / 33 page  Temperature Range Voltage Temperature VREF_MAX VREF_MIN VHYS = lVREF1 - VREF2l VREF x 10 3 mV -40°C VREF1 Time VREF2 25°C 125°C LM4128, LM4128Q www.ti.com SNVS475E – NOVEMBER 2006 – REVISED APRIL 2013 Figure 16. Illustrative Temperature Profile This may be expressed analytically as the following: where • VHYS = Thermal hysteresis expressed in ppm • VREF = Nominal preset output voltage • VREF1 = VREF before temperature fluctuation • VREF2 = VREF after temperature fluctuation (2) The LM4128 features a low thermal hysteresis of 190 µV from -40°C to 125°C. TEMPERATURE COEFFICIENT Temperature drift is defined as the maximum deviation in output voltage over the operating temperature range. This deviation over temperature may be illustrated as shown in Figure 17. Figure 17.
