Figure 2-2 shows the layout of the Voltage Supervisor SOT23 Evaluation Board. This
is a small board (1”x1.2” (25.4 mm x 30.5 mm)) that is single-sided. There are three
connection points (V

The different SOT-23-3 layout options are outlined in the diagram below, with Opt 1,
Opt 2, Opt 3 and Opt 4 indicating the layout option of that SOT-23-3 footprint.
Resistor R1 is a pull-up resistor that may need to be installed for devices with an
open-drain output. Though resistor R2 is not currently required, it was placed for
possible future requirements. Resistor R3, too, is not required, but may be useful if this
board is to be interfaced into existing circuits. If resistor R3 is to be installed, remember
to cut the trace that “shorts out” R3. Capacitors C1 and C2 are bypass capacitors that
may be required to be installed, depending on the device selected and the system
requirements (such as the noise present on the power supply). Table 2-2 describes the
components.
