The VO Adjust control (pin 12) sets the output voltage of the PTH05T210W. The adjustment range of the
PTH05T210W is 0.7V to 3.6V. The adjustment method requires the addition of a single external resistor, RSET,
that must be connected directly between the Vo Adjust and GND pins. Table 1 gives the standard value of the
external resistor for a number of standard voltages, along with the actual output voltage that this resistance value
provides.
For other output voltages, the value of the required resistor can either be calculated using the following formula,
or simply selected from the range of values given in Table 2. Figure 6 shows the placement of the required
resistor.

(1)
Use a 0.05 W resistor. The tolerance should be 1%, with temperature stability of 100 ppm/°C (or better). Place the
resistor as close to the regulator as possible. Connect the resistor directly between pins 12 and 8 using dedicated
PCB traces.
(2)
Never connect capacitors from VO Adjust to either GND or VO. Any capacitance added to the VO Adjust pin affects the
stability of the regulator.
