Product details

The LP3994TLX-1.8 is a fixed-output linear regulator delivering 1.8 V from a standard regulator architecture — no external resistor divider needed for the output setpoint. The fixed voltage means the BOM line is a drop-in for any rail that requires exactly 1.8 V, typical for powering low-voltage logic cores, I/O banks, or sensor bias circuits where a clean, low-noise supply is preferred over a switching converter.

RoHS compliance flag — design-in consideration

For designs governed by RoHS exemptions or destined for markets where RoHS is not enforced, this part is usable as-is. For projects requiring full RoHS compliance, this part is not a fit — a RoHS-compliant variant from the same family should be selected instead.

Bulk packaging — procurement context

The listed package is Bulk, meaning the parts are supplied loose in a bag or tube rather than on a tape-and-reel. This is typical for low-volume production runs, prototyping, or repair stock where pick-and-place volume is not required. For high-volume assembly, a tape-and-reel variant of the same device may be more practical — confirm the packaging preference at order time.
