Rail-to-rail input range from -Vs to +Vs. |+| 2 | -Vs | power_in | Negative power supply. Normally tied to GND. May be tied to a voltage other than GND provided (+Vs) - (-Vs) is 1.8 V to 5.5 V. Bypass with a 0.1 µF capacitor as close to the part as possible when not connected to GND. |+| 3 | -IN | input | Inverting input of the amplifier. Rail-to-rail input range from -Vs to +Vs. |+| 4 | OUT | output | Amplifier output. The voltage range extends to within millivolts of each supply rail (rail-to-rail output). |+| 5 | +Vs | power_in | Positive power supply. Typical range 1.8 V to 5.5 V (single or split supply, provided (+Vs) - (-Vs) is between 1.8 V and 5.5 V). Bypass with a 0.1 µF capacitor between supply pins or from supply to GND as close to the part as possible. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 3PEAK |+| Package | SC-70-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `TP5531U-CR`+- `TP5531U-CRTP5531U-TR`+- `TP5531U-CRTP5531-TR`++## CAD (KiCad official)++- Symbol: `TP5531U-CR`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [3PEAK datasheet](docs/tp5531u-cr-datasheet.pdf) (30 pp, sha256 `19a2f47f502807e1`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
