Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status when sourcing. Confirm the 16-SOIC package dimensions match your PCB footprint requirements. Check current availability status as this component may be discontinued or subject to long lead times depending on the distributor. Ensure the selected variant matches the required thermal performance for your application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductor-less voltage conversion is preferred to save board space. Consider the 25 kHz switching frequency for applications tolerant of lower-frequency noise. Evaluate the 100 mA current limit against peak load demands. Verify that the 16-pin SOIC package fits within the available layout constraints compared to alternative DIP packages.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 series consists of switched-capacitor voltage converters designed for generating bipolar supplies from single sources. The CDWG4 variant specifically denotes the industrial-grade temperature range and green (RoHS/lead-free) compliant version in a surface-mount package. It belongs to the broader LT1054 family which includes various pinout and package options for different integration needs.
