Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix D0R-G against official Torex documentation to confirm the exact output voltage tolerance and packaging type. Ensure compatibility with required thermal management standards for the target application environment. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if restricted substances are a constraint for the end product.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 4.9 V output is required from a single-cell lithium-ion or similar low-voltage source. The 3 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the 800 mA current capability against peak load requirements. Evaluate the SOT-25-5 footprint against available PCB real estate constraints.
