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 | NC | unconnected | No internal connection. Leave floating or tie to a copper pad for mechanical support. |+| 2 | V+ | power_in | Positive supply input. Operating range +11.4VDC to +36VDC; absolute maximum input voltage +40V. Quiescent current 1.4mA max at IOUT = 0. |+| 3 | NC | unconnected | No internal connection. Leave floating. |+| 4 | Com | power_in | Common (ground) return for the reference. Establishes the 0V node from which the +10V VOUT is referenced. |+| 5 | Trim | input | Optional user trim input tapping the internal R5 (~50kOhm) divider. Allows small external adjustment of the output voltage with minimal effect on drift and stability; typical trim range approximately +/-3%. Leave floating if unused. |+| 6 | VOUT | output | +10V precision reference output. Initial accuracy +/-10mV (A), +/-5mV (B), +/-2.5mV (C). Sources up to +10mA and sinks up to -5mA; short-circuit protected to Com or V+. |+| 7 | NC | unconnected | No internal connection. Leave floating. |+| 8 | NR | passive | Noise Reduction pin. Ties to the top of the internal ~7kOhm resistor R6 across the zener. Connect an external capacitor from this pin to Com/ground to form a low-pass filter that rolls off high-frequency zener noise. Leave floating for normal (unfiltered) operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments TI |+| Package | SOIC-8 |+| Category | Power Management ICs |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `REF102AU`+- `REF102BU`+- `REF102CU`+- `REF102AP`+- `REF102BP`+- `REF102CP`++## CAD (KiCad official)++- Symbol: `REF102AU`+- 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:** [Texas Instruments TI datasheet](https://www.ti.com/cn/lit/gpn/ref102) (19 pp, sha256 `5860560fea70aa71`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
