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 | BYPASS | passive | A low-leakage bypass capacitor (NPO/COG ceramic or film recommended) connects here to reduce output noise, and any leakage shifts the regulated output voltage. Bypass pin ESD rating is 500V (LP2988 only). |+| 2 | DELAY | passive | A single external capacitor sets the power-on reset delay, charged by a 2.2 µA source, with a maximum recommended value of 1 µF and no aluminum electrolytics; the Delay pin is ESD rated at 1.5kV. |+| 3 | GROUND | power_in | Ground return pin for the regulator. |+| 4 | INPUT | power_in | Unregulated supply input with an operating range of 2.1V to +16V (survival −0.3V to +16V), requiring an input capacitor of at least 2.2 µF located within 0.5 inch of the pin. |+| 5 | ERROR | output | Open-collector error/reset flag that goes low when the output drops about 5% below nominal and requires an external pull-up resistor; its absolute maximum voltage is −0.3V to +16V. |+| 6 | SHUTDOWN | input | Driving this pin low turns the regulator off and driving it high turns it on, with a slew rate of at least 40 mV/µs required and an absolute maximum of −0.3V to +16V; tie it to INPUT if the feature is not used. |+| 7 | OUTPUT | power_out | Regulated 5.0V output rated for 200 mA continuous and more than 250 mA peak, requiring a minimum of 4.7 µF output capacitance with ESR within the stable range and an absolute maximum of −0.3V to +16V. |+| 8 | SENSE | input | Sense input for the output voltage feedback, rated −0.3V to +6V absolute maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `LP2988IMX-5.0`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `lp2988imx-5-0-etched.step` / `lp2988imx-5-0-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lp2988imx-5-0.step` / `lp2988imx-5-0.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/lp2988) (38 pp, sha256 `79f49a22be2bfe07`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
