Product details

The LM385PW-2-5: This means new-design wins should choose a current-production alternative; existing BOM lines must source through the independent surplus channel.

2.5V fixed shunt — the core spec

The shunt topology means it behaves like a two-terminal Zener — it regulates by shunting current away from the load through the cathode. Minimum cathode current is 20 µA, maximum output current is 20 mA, so the total current through the device plus load must stay within that ceiling.

Sourcing reality for an obsolete part

No official replacement or second-source alternate is listed on the Texas Instruments record for this exact suffix.
