Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the ordering quantity matches the manufacturer's standard reel size to avoid cut-tape discrepancies. Cross-reference the datasheet revision date to confirm technical accuracy.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 20 V is required alongside a 2 A output capacity. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 10-MSOP package dimensions for PCB layout constraints. Verify that the application environment stays within the specified -40°C to +125°C operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2734x family of wide-input-range buck regulators from Texas Instruments.
