Product details

What this 1.8V LDO brings to the board

The Texas Instruments LP3876ESX-1.8/NOPB is a single-output positive LDO that delivers a fixed 1.8 V at up to 3 A. It is built for industrial and automotive-adjacent environments where the ambient temperature can hit 125 °C and the load demands a clean, regulated rail without a lot of headroom. The D²Pak (TO-263-5) package has a large metal tab that sinks heat into the board copper — you will want a decent copper pour under that tab if you plan to pull the full 3 A continuously.

Protection and control for field reliability

Built-in over-current, over-temperature, and short-circuit protection mean this regulator can survive a fault on the output without letting the magic smoke out. The Enable pin lets you sequence the rail on and off — handy if the downstream load needs a power-on reset or you are ganging multiple regulators. Quiescent current runs 5 mA typical, supply max 15 mA; not a low-Iq part for battery gear, but fine for a powered system where the 3 A capability is the draw.

Sourcing and lifecycle

The LP3876ESX-1.8/NOPB is listed as Active and ROHS3 compliant.

Frequently asked questions

What is the equivalent of LP3876ESX-1.8/NOPB?

There is no single drop-in equivalent listed. The LMS1587IS-3.3/NOPB is a 3.3 V, 3 A LDO in a similar TO-263 package but with a different output voltage. For a 1.8 V, 3 A fixed LDO, the LP3876ESX-1.8/NOPB is the primary part; check the TPS7A0218PYCHR for a lower-current (200 mA) alternative.
