6.1 Input/Output Connectors and Jumper Descriptions
6.1.1 J16 – VIN
Input power-supply voltage connector. This is the jumper power-supply connection for the DBV package
on the MultiPkgLDOEVM-823. Connect the load of the LDO to this pin.
6.1.2 J17 – VOUT
Output power-supply voltage connector. This is the jumper power-supply connection for the DBV package
on the MultiPkgLDOEVM-823. Connect the power supply to this jumper pin.
6.1.3 J18 – EN
Output enable. To enable the output, connect a jumper to short VIN to EN.
6.1.4 J19 – GND
GND jumper. Connect the GND leads of the input power supply to this jumper.
6.1.5 J20 – GND
GND jumper. Connect the GND leads of the load to this jumper.
6.1.6 TP16 – VIN
Input test point. Connect DMM or scope probes to this point to monitor the input voltage of the LDO.
6.1.7 TP17 – VOUT
VOUT test point. Connect DMM or scope probes to this point to monitor the output of the LDO.
6.1.8 TP18 – EN
This test point connects to EN. When J3 is removed, this testpoint can be used to drive the EN pin of the
LDO.
6.1.9 TP19 – GND
GND test point. Connect GND lead of scope probes and power supply to this point.
6.1.10 TP20 – GND
GND test point. Connect GND lead of scope probes and power supply to this point.
6.2 Component Descriptions
6.2.1 C10 - Input Capacitor
Populate the recommended input capacitor for the part that is being used.
6.2.2 C11 - Feedforward Capacitor
Populate the recommended feedforward capacitor for the part that is being used. Feedforward capacitors
can only be used on adjustable LDOs, consult the data sheet for the proper feedforward capacitor.
