The VOAdjust control (pin 5) sets the output voltage of the PTH12030W/L. The adjustment range is 1.2V to 5.5V
for the W-suffix modules, and 0.8V to 1.8V for L-suffix modules. The adjustment method requires the addition of
a single external resistor, RSET, that must be connected directly between the VOAdjust and GND pins
(1). 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 required resistor can either be
calculated using Equation 1, or simply selected from the range of values given in Table 3. Figure 10 shows the
placement of the required resistor.

Figure 10. Vo Adjust Resistor Placement
1. RSET: Use a 0.05 W resistor with a tolerance of 1% and temperature stability of 100 ppm/C (or better).
Connect the resistor directly between pins 5 and 7, as close to the regulator as possible, using dedicated
PCB traces.
2. Never connect capacitors from VOAdjust to either GND or VO. Any capacitance added to the VO Adjust pin
affects the stability of the regulator.
