1.2.2
Jumper JP1 connects the input capacitance to the circuit. The input capacitor is
disconnected when performing Power Supply Ripple Rejection tests. By default, C1 is
populated with a 1 µF, 50V, XR7 ceramic capacitor.
1.2.3
Jumper JP2 allows the user to select the Shutdown (SHDN) pin voltage level. The
voltage level may be set to V
jumper. When the jumper is not connecting pins 1 and 2 or pins 2 and 3 of JP2, the
voltage level may be set by attaching a signal to TP5. This allows the user to enable,
disable or pulse the shutdown pin of the device.
The board comes with R1 populated with a 10 kΩ resistor.
1.2.4
Jumper JP3 allows measurement of ground current. When a current meter is
connected to TP6 and TP7 and jumper JP3 is removed, the ground current of the
device may be measured.
1.2.5
For Adjustable Output Voltage devices, R2 and R3 may be populated with appropriate
values to provide the desired output voltage.
The board comes with R2 populated with a 69.8 kΩ resistor.
1.2.6
For devices with a Power Good (PWRGD) output, either R2 or R4 is populated
depending on the desired pull-up source voltage.
R2 selects V
R4 selects V
The board comes with R2 populated with a 69.8 kΩ resistor.
1.2.7
R5 may be populated with the desired load resistor values for the device being
evaluated. Jumper JP4 connects R5 to the device output.
1.2.8
C2 may be populated with the desired output capacitance. By default, C2 is populated
with a 1 µF, 6.3V, XR7 ceramic capacitor.
1.2.9
C3 may be populated with the desired bypass capacitance.
1.2.10
J1 or TP1 and TP2 are connected to the user’s power supply.
