5.1 Input/Output Connectors and Jumper Descriptions
5.1.1 J11 – VIN
Input power-supply voltage connector. This is the jumper power-supply connection for the DQN package
on the MultiPkgLDOEVM-823. Connect the load of the LDO to this pin.
5.1.2 J12 – VOUT
Output power-supply voltage connector. This is the jumper power-supply connection for the DQN package
on the MultiPkgLDOEVM-823. Connect the power supply to this jumper pin.
5.1.3 J13 – GND
GND jumper. Connect the GND leads of the input power supply to this jumper.
5.1.4 J14 – EN
Output enable. To enable the output, connect a jumper to short VIN to EN.
5.1.5 J15 – GND
GND jumper. Connect the GND leads of the load to this jumper.
5.1.6 TP11 – VIN
Input test point. Connect DMM or scope probes to this point to monitor the input voltage of the LDO.
5.1.7 TP12 – VOUT
VOUT test point. Connect DMM or scope probes to this point to monitor the output of the LDO.
