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 | power_out | Regulated 3.0 V ±1.5% output voltage with 100 mA maximum sourcing capability; typical 50 mV dropout at light load and 380 mV dropout at 100 mA. |+| 2 | SENSE | input | Output voltage sense input for remote load sensing; tie to OUT pin for fixed voltage fixed regulator operation or connect to remote load for compensation. |+| 3 | SHUTDOWN | input | Logic-controlled shutdown input; pull low (≤0.7 V) to enable regulator or high (≥2 V) to disable and reduce quiescent current to 3-10 µA. |+| 4 | GND | power_in | Ground reference and power return for all internal circuits; connect DAP (exposed pad on WSON) to this ground pin. |+| 5 | ERROR | tri_state | Open-collector error flag output; pulls low when regulated output drops below 95% nominal (about 2.85 V for 3 V version) due to dropout, overcurrent, or thermal limiting. |+| 6 | VTAP | output | Internal reference divider output at nominal 1.235 V; connect to FEEDBACK pin for fixed voltage or use in external resistor network for programmable output voltage. |+| 7 | FEEDBACK | input | Voltage feedback input for programmable or fixed output mode with typical bias current of -20 nA; tie to VTAP for fixed 3 V output or set with external resistors for 1.24 V to 29 V. |+| 8 | IN | power_in | Input supply voltage ranging from 2.3 V to 30 V; requires minimum 1 µF input capacitor if source is >10 inches distant or battery powered. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `LP2951ACMX-3.0`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `lp2951acmx-3-0-etched.step` / `lp2951acmx-3-0-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lp2951acmx-3-0.step` / `lp2951acmx-3-0.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lp2951-n) (62 pp, sha256 `b9e1f8851a20b9c9`, retrieved 2026-09-23, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5` (agreed), guards: pin_guards 0.1: passed.
