Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and specific tape-and-reel packaging configuration. Ensure the ordering code matches the required package variant and temperature grade. Cross-reference the manufacturer datasheet revision history to confirm current manufacturing status and any potential form-fit-function changes associated with recent production updates.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output synchronous buck converter is required with an input voltage up to 38 V. Consider the 1.5 A output capability and 16 V maximum output limit against load demands. Evaluate the 16-lead HTSSOP package dimensions for PCB space constraints. Confirm that the fixed or programmable switching frequency options align with electromagnetic interference requirements and inductor selection criteria.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM26001 family of synchronous buck regulators from Texas Instruments. It shares architectural similarities with other members like the LM26003 but differs in output current capacity and pin count. The family targets general-purpose DC/DC conversion applications where efficiency and board space are critical factors. It complements higher-current variants and lower-power alternatives within the broader power management portfolio.
