(4) A total capacitance of 540 µF is acceptable based on the combined ripple current rating.

(5) Ceramic capacitors are required to complement electrolytic types at the input and to reduce high-frequency ripple current.

The VO Adjust control (pin 4) sets the output voltage of the PTH12060 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 pins.

Table 2 gives the preferred value of the external resistor for a number of standard voltages, along with the actual

output voltage that the resistance value provides. Figure 9 shows the placement of the required resistor.
