Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DDCR against the official Texas Instruments datasheet to confirm the tape-and-reel packaging configuration. Ensure compatibility with standard SMD reflow processes for the SOT-23-THIN-6 package. Confirm RoHS compliance status through the manufacturer's environmental documentation prior to integration into regulated assemblies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a variable input source between 2.7 V and 5.5 V. The inductorless design simplifies PCB layout compared to traditional inductive converters. Consider the 60 mA output limit and 65 uA quiescent current for low-power applications. Verify thermal performance within the specified -40°C to +85°C ambient range for the target environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the REG71050 family of charge pump regulators from Texas Instruments. It shares architectural similarities with other variants like the REG71050DDCT and REG71050DRVR, differing primarily in packaging and reel quantities. The REG71050 series is designed for space-constrained portable applications where inductor-free solutions are preferred over magnetic components.
