Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix '14R-G' against the manufacturer's latest datasheet to confirm the specific output voltage and package variant. Ensure compatibility with the required PCB footprint for the 6-USPEL exposed pad package. Cross-reference RoHS compliance status if environmental regulations apply to your manufacturing process. Confirm availability through authorized distributors as stock levels fluctuate.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.1 V output is required from a variable or low input source. The synchronous design offers better efficiency than asynchronous alternatives at similar current levels. Consider the 100 mA output limit and ensure it meets the load requirements. The wide input range allows operation from nearly depleted batteries down to 0.9 V.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9140 family of high-efficiency step-up converters. The series includes various output voltage options and package types, such as SOT-25 and X2SON. The XC9140C2114R-G specifically denotes the 2.1 V fixed output version in the USP-EL-EP-6 package.
