Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LDER against the manufacturer's official datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with the required 2.85 V output specification. Check RoHS compliance documentation for environmental standards. Confirm availability status as distribution channels may indicate restricted supply or regional limitations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.85 V output is required from a 2.5 V to 5.5 V input source. The 3 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 15 uA quiescent current for battery life optimization. Verify that the USP-C-EP-6 package fits the PCB layout constraints.
