8.3.2 LDO Operation

An internal LDO allows the driver to run off higher voltages from 6 V to 18 V and regulates the supply to 5 V, so the LMG1210 can run off of higher input voltages with wide tolerances. To maintain stability of the internal LDO, care must be taken to make sure a capacitor of at least 0.3 µF from VDD to VSS with an ESR below 500 mΩ is used. A high-quality ceramic capacitor with an X7R dielectric is recommended. There is no maximum limit on the capacitance allowed on the output of the LDO.

If the input supply is already 5 V ±5%, then the LDO can be bypassed. This is achieved by connecting the 5 V supply directly to the VDD pin. The VIN pin should be tied to the VDD pin, and the capacitor on the VIN pin can be removed. Do not ground the VIN pin.
