Voltage Supervisor Evaluation Board ( VSUPEV )

The Voltage Supervisor SOT23 Evaluation Board allows the system designer to quickly evaluate the operation of Microchip’s Voltage Supervisors and Voltage Detectors in the SOT-23-3 package. The board has been made generic so that other SOT-23-3 devices (such as LDOs and Voltage References) may also be evaluated using this board. This kit comes with four blank PCBs to allow the designer to...
