Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground reference. |+| 2 | SD | input | Active-low shutdown input that tri-states VTT while maintaining VREF active and reducing quiescent current; has internal pullup. |+| 3 | VSENSE | input | Feedback input for remote load regulation of VTT; connect to middle of termination bus or to VTT output if remote regulation not used. |+| 4 | VREF | power_in | Buffered output of VDDQ/2 reference for Northbridge and memory; remains active during shutdown and thermal shutdown. |+| 5 | VDDQ | power_in | Input for internal reference generating VTT = VDDQ/2 via two 50-kΩ internal resistors; optimal connection is directly to 2.5-V rail at DIMM. |+| 6 | AVIN | power_in | Power supply input for internal control circuitry; must be ≥ PVIN and typically connected to 2.5-V with PVIN for SSTL-2 applications. |+| 7 | PVIN | power_in | Power input for output stage; must be ≤ AVIN; higher values increase maximum continuous output current up to 1.5 A but increase power dissipation. |+| 8 | VTT | tri_state | Regulated output for termination resistors capable of sourcing and sinking up to ±3 A peak current; tri-states during shutdown or thermal shutdown. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `LP2996MX`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `lp2996mx-etched.step` / `lp2996mx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lp2996mx.step` / `lp2996mx.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/lp2996-n) (42 pp, sha256 `7893016d1b8b5962`, retrieved 2026-10-03, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
