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 | Amplifier output. Rail-to-rail output swing; typical output current 48mA at V+=5V; closed-loop output impedance ~2.6Ω at 100kHz. |+| 2 | -Vs | power_in | Negative supply rail (typically GND in single-supply operation). Supply voltage range 2.5V to 5.5V referenced between +Vs and -Vs. |+| 3 | +IN | input | Non-inverting analog input. Common-mode range -0.1V to (V+)+0.1V (rail-to-rail); input bias current typically 1pA. |+| 4 | -IN | input | Inverting analog input. Common-mode range -0.1V to (V+)+0.1V; input offset voltage typically 0.7mV (±3.5mV max). |+| 5 | +Vs | power_in | Positive supply rail. Operating range 2.5V to 5.5V; absolute maximum 7.5V. Recommended bypass with 10µF and 0.1µF capacitors to -Vs. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | DIOO |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `DIO20321ST5`+- `DIO20321ST5SO8`+- `DIO20321ST5MP8`+- `DIO20321ST5TP8`+- `DIO20321ST5SO14`+- `DIO20321ST5TP14`+- `DIO20321ST5QN20`++## CAD (KiCad official)++- Symbol: `DIO20321ST5`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [DIOO datasheet](docs/dio20321st5-datasheet.pdf) (8 pp, sha256 `7c7f8bb428c64ba3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
