Npct750 Datasheet Guide

Extracting the maximum PSRR and lowest noise from the NPCT750 depends heavily on PCB layout. The datasheet will emphasize these points:

| Symptom | Likely Cause | Solution from Datasheet | |---------|--------------|--------------------------| | Output voltage lower than expected | Inadequate load regulation due to thin traces | Widen output trace, measure at IC pin | | Excessive ripple/noise on output | Missing or wrong ESR output capacitor | Use low-ESR ceramic (X7R) with recommended value | | IC shuts down intermittently | Thermal cycling, insufficient copper heat sink | Add thermal vias, increase copper area, reduce load | | Output overshoot at startup | Capacitor on BYP pin too large | Keep Cbypass ≤ 10nF | | Oscillation on output | Too much capacitance on output | Some LDOs require a minimum ESR; add a 0.5Ω resistor in series with COUT | npct750 datasheet
