Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the obsolete status of this component before procurement planning, as it may no longer be manufactured by Texas Instruments. Confirm availability through authorized distributors or secondary market channels if immediate supply is required. Ensure that the 8-pin USMD package matches your board design constraints. Check for lead times associated with end-of-life products and consider long-term supply chain risks when integrating this part into new designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select the LM2787BP/NOPB when a negative adjustable voltage rail is needed with low output current requirements up to 10mA. Consider its charge pump topology for applications where inductor-based solutions are undesirable due to size or EMI constraints. Evaluate the operating temperature range and package type against your environmental and spatial requirements. Compare performance metrics such as ripple and efficiency against alternative regulators if higher current or different voltage polarities are needed.
