Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and RoHS status. Confirm the 'IMX' suffix corresponds to the VSSOP-8 tape-and-reel packaging format required for automated assembly. Cross-reference the specific revision level against the manufacturer's latest datasheet to ensure compatibility with current design specifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5 V output is required alongside ultra-low quiescent current consumption. The integrated reset function simplifies board design by eliminating external reset ICs. Ensure the input voltage remains above the minimum threshold of 2.1 V while accounting for the dropout voltage under maximum load conditions to maintain regulation stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the LP2988 series of micropower LDO regulators. It shares the core electrical characteristics with the LP2988IMM variant but utilizes different packaging.
