SLTS231C – NOVEMBER 2004 – REVISED FEBRUARY 2007
The VO Adjust control (pin 8) sets the output voltage of the PTV12020 product. The adjustment range is from
1.2 V to 5.5 V for the W-suffix modules and 0.8 V to 1.8 V for L-suffix modules. The adjustment method requires
the addition of a single external resistor, RSET, that must be connected directly between the VO Adjust and GND
(pin 1 or 2). 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 Equation 1 or simply selected from the range of values given in
Table 3.Figure 11 shows the placement of the required resistor.

(1)
A 0.05-W rated resistor may be used. 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 pin 8 and pins
1 or 2, using dedicated PCB traces.
(2)
Never connect capacitors from VoAdj to either GND or Vo. Any capacitance added to the VoAdj pin affects the
stability of the regulator.
