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 input supply, +2.5 V to +16 V recommended (absolute max -20 V to +20 V, reverse-battery protected). Bypass with a 1 uF capacitor close to the pin. |+| 2 | GND | power_in | Device ground return. Ground pin current ranges from ~70 uA at IL=100 uA up to ~1.3 mA at IL=150 mA. |+| 3 | EN | input | Active-high enable input. VIH >= 2.0 V turns the regulator ON; VIL <= 0.4 V places it in zero-off-mode. Input range 0 V to VIN (abs max -20 V to +20 V). May be tied directly to VIN for always-on operation. |+| 4 | BYP/ADJ | bidirectional | On the adjustable version (SPX5205M5-L/TR, top mark H1WW) this pin is ADJ: feedback node tied to the R1/R2 divider from VOUT to set VOUT = 1.235 V x (1 + R1/R2); R2 must be > 10 kohm (22-47 kohm recommended). On fixed-output variants it is BYP: exposes the internal 1.235 V reference for a 10 nF noise-bypass capacitor to GND, dropping output noise to ~40 uVRMS. Larger CBYP slows start-up; may be left open if noise is not critical. |+| 5 | VOUT | power_out | Regulated LDO output, 150 mA max, 1% initial accuracy. Requires an output capacitor for stability (1 uF tantalum or 2.2 uF aluminum electrolytic typical). Current limited to ~360-500 mA and thermally protected. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SPX5205M5-LM5-L/TR`+- `SPX5205M5-LM5-L-1-2/TR`+- `SPX5205M5-LM5-L-1-8/TR`+- `SPX5205M5-LM5-L-2-5/TR`+- `SPX5205M5-LM5-L-3-0/TR`+- `SPX5205M5-LM5-L-3-3/TR`+- `SPX5205M5-LM5-L-5-0/TR`++## CAD (KiCad official)++- Symbol: `SPX5205M5-L`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MaxLinear datasheet](docs/spx5205m5-l-datasheet.pdf) (8 pp, sha256 `421c6d60c0a5736f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
