LM317L is a low-current adjustable positive linear regulator. Its floating reference and two external resistors set an output near 1.25 V or above, while the series pass stage supplies up to 100 mA under the applicable differential-voltage and thermal conditions. The three-lead TO-92 and eight-lead SOIC have different physical layouts. TO-92 uses INPUT 1, OUTPUT 2 and ADJUST 3; SOIC uses INPUT 1, ADJUST 4 and four internally connected OUTPUT pins, 2, 3, 6 and 7. The package switch updates every view and the footprint. TI SLCS144G distinguishes legacy SHE/TID chips from the new RFB chip. TO-92 remains legacy-only. The tables retain these distinctions rather than assigning the newer 45 V stress limit to every part. A 9 V input, 220 Ω / 660 Ω divider and 500 Ω load illustrate a modest near-5 V supply.
