9 Power Supply Recommendations

The device is designed to operate from an input voltage supply range between VOUT + 1 V up to a maximum of

26 V. This input supply must be well regulated and free of spurious noise. To ensure that the LM2941 output

voltage is well regulated, the input supply should be at least VOUT + 2 V.

10 Layout

10.1 Layout Guidelines

The dynamic performance of the LM2941 is dependent 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 LM2941. Best

performance is achieved by placing CIN and COUT on the same side of the PCB as the LM2941, and as close as

is practical to the package. The ground connections for CIN and COUT should be back to the LM2941 ground pin

using as wide and short of a copper trace as is practical.
