Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix C0R-G to confirm the fixed 2.7V output voltage and WLP-5-03-5 packaging configuration. Ensure compatibility with RoHS directives and check for moisture sensitivity level requirements during storage and handling. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for stepping down 2V to 6V inputs to a precise 2.7V output. The choice is driven by the need for small footprint via the WLP package and high efficiency at moderate load currents up to 600mA. Consider the 1.2MHz switching frequency for balancing component size and electromagnetic interference.
