MCP1726 LDO Evaluation Board
MCP1726 LDO Evaluation Board ( MCP1726EV )

The MCP1726 1A LDO Evaluation Board features Microchip Technology’s 1A, Low Quiescent Current LDO Regulator in two circuits. The first circuit has the adjustable version of the MCP1726 in the 8-pin 3X3 DFN package. The second circuit has the adjustable version of the MCP1726 in the 8-pin SOIC package. Both circuits have potentiometers that can be used to adjust the output voltage of the LDO....

8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board ( SOIC8EV )

This is a blank PCB that allows the operation of Microchip Technology’s 8-pin devices to be easily evaluated. Each device pin is connected to a pull-up resistor, a pull-down resistor, an in-line resistor, and a loading capacitor. The PCB pads allow through hole or surface mount connectors to be installed to ease connection to the board. Additional passive component footprints are on the...
