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 | OUT | output | Regulator switching output. Connects to the external inductor/catch-diode node of the buck converter; delivers up to 1A at 1.2V-35V. |+| 2 | SYNC | bidirectional | Master/slave synchronization pin. Allows synchronizing multiple regulators to a common switching frequency. Absolute max -0.3 to 4V. |+| 3 | INH | input | Inhibit input (active high). A logic high disables the device. If unused, must be grounded; when left open, an internal pull-up disables the device. Absolute max -0.3V to Vcc. |+| 4 | COMP | output | Error amplifier output for loop/frequency compensation. Connect external RC compensation network (typ. 4.7kΩ + 22nF with 220pF shunt). |+| 5 | FB | input | Feedback input. Tying FB directly to the output yields a 1.23V output; an external resistive divider is required for higher output voltages. Absolute max 4V. |+| 6 | VREF | power_out | 3.3V (±2%) reference voltage output. No external stabilization capacitor is required. |+| 7 | GND | power_in | Device ground return. |+| 8 | VCC | power_in | Unregulated DC input supply, 4.4V to 36V operating (40V absolute max). Bypass with a low-ESR ceramic input capacitor (e.g. 10µF/35V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `L5970D013TRL5970D`+- `L5970D013TR`++## CAD (KiCad official)++- Symbol: `L5970D013TR`+- 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/l5970d013tr.pdf) (17 pp, sha256 `d13c9acf63805d28`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
