Cathode and Load Currents
In a typical shunt-regulator configuration (see Figure 3), an external resistor, RS, is connected between the
supply and the cathode of the TL4050. RS must be set properly, as it sets the total current available to supply the
load (IL) and bias the TL4050 (IZ). In all cases, IZ must stay within a specified range for proper operation of the
reference. Taking into consideration one extreme in the variation of the load and supply voltage (maximum IL and
minimum VS), RS must be small enough to supply the minimum IZ required for operation of the regulator, as
given by data-sheet parameters. At the other extreme, maximum VS and minimum IL, RS must be large enough
to limit IZ to less than its maximum-rated value of 15 mA.
RS is calculated according to Equation 1:
