Universal Low-Dropout (LDO) Linear Voltage Regulator MultiPkgLDOEVM-
823 Evaluation Module

4.2.3

C7 - Output Capacitor

Populate the recommended output capacitor for the part that is being used.

4.2.4

R3 - RTOP

This is the top feed back resistor. Populate with the resistance value that will give the desired output. See
the data sheet for the equation to calculate R3. This resistor is only necessary for adjustable LDOs.

4.2.5

R4 - RBOT

This is the bottom feed back resistor. Populate with the resistance value that will give the desired output.
See the data sheet for the equation to calculate R4. This resistor is only necessary for adjustable LDOs.
