Product details

100 mA adjustable rail for local regulation

The Texas Instruments LM317LID is an adjustable positive voltage regulator delivering up to 100 mA, with an output adjustable from 1.2 V to 32 V. It is a surface-mount variant of the classic LM317 family in an 8-SOIC package, suited for generating a clean local rail from a higher unregulated supply up to 38 V input.

PSRR and protection in harsh environments

PSRR is specified at 80 dB typical at 120 Hz, dropping to 65 dB — this matters for attenuating rectified mains ripple in audio, instrumentation, or sensor bias supplies. The regulator includes over-current, over-temperature, and short-circuit protection, reducing the need for external clamp or foldback circuits.

Frequently asked questions

What is the difference between LM317LID and LM317L?

The LM317LID is the surface-mount 8-SOIC version of the LM317L, which is typically offered in a through-hole TO-92 or TO-220 package. The electrical specifications — 100 mA output, 1.2 V to 32 V range, PSRR, and protection features — are shared; the package is the primary differentiator for board assembly.
