10 Layout

10.1 Layout Guidelines

The dynamic performance of the LP5907 is dependant on the layout of the PCB. PCB layout practices that are

adequate for typical LDOs may degrade the PSRR, noise, or transient performance of the LP5907.

Best performance is achieved by placing CIN and COUT on the same side of the PCB as the LP5907, and as

close to the package as is practical. The ground connections for CIN and COUT must be back to the LP5907

ground pin using as wide and short a copper trace as is practical.

Connections using long trace lengths, narrow trace widths, and/or connections through vias must be avoided.

These add parasitic inductances and resistance that results in inferior performance especially during transient

conditions
