VOLTAGE SUPERVISOR SOT23 EVALUATION BOARD DESCRIPTION
The Voltage Supervisor SOT23 Evaluation Board PCB is designed to be flexible in the
type of device evaluation that can be implemented.
The following sections describe each element of this evaluation board in further detail.
2.4.1
Power and Ground
The Voltage Supervisor SOT23 Evaluation Board can have connection posts installed
for the power (V
DD
) and ground (V
SS
) planes. The layout allows either through-hole or
surface-mount connectors.
For device evaluation, the use of an external variable power supply or waveform
generator is required. The type of equipment used will determine the evaluation that
may be performed.
2.4.2
Output (V
OUT
)
The Voltage Supervisor SOT23 Evaluation Board can have a connection post installed
for the output (V
OUT
) signal. The layout allows either a through-hole connector or a
surface mount connector.
For device evaluation, the use of an oscilloscope or digital volt meter (DVM) is required.
The type of equipment used will determine the evaluation that may be performed.
2.4.3
SOT-23-3 Footprints
There are four SOT-23-3 pinout options that the Voltage Supervisor SOT23 Evaluation
Board PCB supports. Figure 2-3 shows these four pinouts. Some devices may use dif-
ferent nomenclature for the pin names, such as GND instead of V
SS
, V
IN
instead of V
DD
and RESET (or RESET) or RST instead of V
OUT
.
Other Microchip analog devices may be used with this PCB if the power and ground
pins match one of these four options.
Appendix C. “Microchip Analog SOT-23
discusses other Microchip analog devices that may be used
with this PCB.

Passive Components (C1, C2, R1, R2 and R3)
The footprints for these components are present to allow maximum flexibility in the use
of this PCB to evaluate a wide range of SOT-23-3 devices. The purpose of these com-
ponents may vary depending on the device under evaluation and how it is to be used
in the desired circuit. Please refer to the device data sheet for the components that
should be used when using that device.
