Application Notes
PTH03000W
Adjusting the Output Voltage of the PTH03000W
Wide-Output Adjust Power Modules
The V o Adjust control (pin 4) sets the output voltage of
Table 2-2; Output Voltage Set-Point Resistor Values
the PTH03000Wproduct. The adjustment range is
from 0.9 V to 2.5 V. The adjustment method requires
the addition of a single external resistor, R set , that must
be connected directly between the V o Adjust and GND
pins 1 . Table 2-1 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 2-2.
Figure 2-1 shows the placement of the required resistor.

Notes :
1. Use a 0.1 W resistor. The tolerance should be 1 %,
with a 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 1
using dedicated PCB traces.
Figure 2-1; V o Adjust Resistor Placement
2. Never connect capacitors from V o Adjust to either GND or
V out . Any capacitance added to the V o Adjust pin will affect
the stability of the regulator.
