7.3 Adjustable Version

The adjustable version allows VZ to be set by a user-defined resistor divider. The output voltage, VZ, is set according to the equation shown in Figure 7-3.

TL4051 Adjustable Shunt RegulatorFigure 7-3 Adjustable Shunt Regulator

When the output voltage, VZ, is set below 2.5V on adjustable versions of TL4051, the device can experience increased reference voltage change with output voltage change (ΔVREF/ΔVKA) when compared to output voltages set equal to or above 2.5V
