Adjusting the Output Voltage of the PTH03060W &
PTH05060W Wide-Output Adjust Power Modules
The Vo Adjust control (pin 4) sets the output voltage of the
PTH03060W and PTH05060W products to a value higher
than 0.8 V. The adjustment range of the PT03060W
(3.3-V input) is from 0.8 V to 2.5 V 1, and the PTH05060W
(5-V input) from 0.8 V to 3.6 V. For an output voltage
other than 0.8 V a single external resistor, Rset, must be
connected directly between the Vo Adjust and GND pins 2.
Table 1-1 gives the preferred 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 1-2.
Figure 1-1 shows the placement of the required resistor.

Notes:
1. Modules that operate from a 3.3-V input bus should
not be adjusted higher than 2.5 V.
2. Use a 0.1 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 4 and 7 using dedicated
PCB traces.
3. Never connect capacitors from Vo Adjust to either GND or
Vout. Any capacitance added to the Vo Adjust pin will affect
the stability of the regulator.
