Product details

100 mA adjustable regulator with industrial temperature range

The LM317LILPR is a positive adjustable voltage regulator from Texas Instruments, delivering up to 100 mA output current with a 1.2 V to 32 V output range from a 38 V maximum input. Built-in protection includes over-current, over-temperature, and short-circuit — the same fault handling you expect from the LM317 family, scaled for lower current.

PSRR is specified at 80 dB to 65 dB at 120 Hz. Quiescent current is 2.5 mA typical.

Package and mounting — the formed-lead TO-92-3

The TO-92-3 formed-lead variant uses the same three-pin footprint as the standard LM317LZ TO-92, with leads pre-formed for vertical board insertion or socket mounting.

For BOM lines that need this exact current rating and package, it's a safe selection for ongoing builds.

Frequently asked questions

Is LM317LILPR pin-compatible with the standard LM317LZ?

Yes — the LM317LILPR uses the same TO-92-3 pinout as the LM317LZ. The three leads (adjust, output, input) are in the same order. The difference is the formed leads on the LILPR variant, which are pre-bent for vertical mounting; the LZ has straight leads. Electrically they are interchangeable within the 100 mA rating.
