LM4030 SNVS552B – MARCH 2008 – REVISED APRIL 2013 www.ti.com Figure 23. Reverse Dynamic Impedance vs COUT As with other regulators, an external capacitor reduces the amplitude of the VREF transient when a sudden change in loading takes place. The capacitor should be placed as close to the part as possible to reduce the effects of unwanted board parasitics. THERMAL HYSTERESIS Thermal hysteresis is the defined as the change in output voltage at 25°C after some deviation from 25°C.

LM4030 www.ti.com SNVS552B – MARCH 2008 – REVISED APRIL 2013 TEMPERATURE COEFFICIENT Temperature drift is defined as the maximum deviation in output voltage over the temperature range. This deviation over temperature may be illustrated as shown in Figure 25. Temperature Change in Output Voltage Voltage VREF_MAX VREF_MIN Temperature Range Figure 25.
