Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the 6-USON package dimensions match your PCB footprint requirements. Ensure the fixed 1.82 V output aligns with your target rail voltage needs before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.82 V output is required from a single-cell lithium-ion or similar battery source. The 3 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the 600 mA current limit for load requirements and the 6-USON package for spatial constraints.
