Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VIN | power_in | Unregulated positive input supply. Input-to-output differential up to 40 V max. A 0.1 uF bypass capacitor to ground is recommended near the pin. |+| 2 | VOUT | power_out | Regulated output. Adjustable from 1.2 V to 37 V; delivers up to 100 mA of load current. Requires a minimum load current (typ. 3.5 mA) for regulation. |+| 3 | VOUT | power_out | Regulated output (internally tied to pin 2). SO-8 doubles the output pin for improved current handling and thermal performance. |+| 4 | ADJ | input | Adjustment pin. Connects to the top of the external resistor divider that sets Vout = Vref x (1 + R2/R1) + Iadj x R2, with Vref = 1.25 V typ. Adjust pin current is 50 uA typ (100 uA max). |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to a copper pour for mechanical support. |+| 6 | VOUT | power_out | Regulated output (internally tied to pins 2 and 3). SO-8 provides three output pins for improved current handling and thermal dissipation. |+| 7 | VOUT | power_out | Regulated output (internally tied to pins 2, 3, and 6). SO-8 pins 2/3/6/7 are all the regulator output. |+| 8 | NC | unconnected | No internal connection. Leave floating or tie to a copper pour for mechanical support. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `LM217LD13TR`+- `LM217LD13TRLM317LD13TR`+- `LM217LD13TRLM317LZ`+- `LM217LD13TRLM317LZ-AP`+- `LM217LD13TRLM317LZ-TR`+- `LM217LD13TRLM217LZ-TR`++## CAD (KiCad official)++- Symbol: `LM217LD13TR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/lm217ld13tr.pdf) (23 pp, sha256 `6f70ef728068a972`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
