Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part number matches LT1054IDWG4 exactly, including the G4 suffix indicating lead-free and RoHS compliance. Check datasheet revisions for any updates to electrical characteristics or pinout definitions before integration into final designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, low-cost solution for generating a regulated negative voltage from a positive input is required. Consider the 100 mA output limit and 25 kHz switching frequency against system noise and size constraints. Ensure the SOIC-16 package fits the PCB layout and thermal requirements of the application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 series belongs to Texas Instruments' portfolio of switched-capacitor voltage converters. The IDWG4 variant specifically denotes the industrial temperature grade (-40°C to +85°C) packaged in a 16-pin SOIC format. This family is designed for applications needing simple, efficient voltage inversion or multiplication without magnetic components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1054IDW is a compatible non-RoHS version with identical electrical specifications. LT1054CDWG4 is a discontinued alternative; verify availability and parameter equivalence if considering substitution. Always cross-reference pinouts and thermal performance before replacing.
