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 | GND_F | power_in | Ground force pin. Analog output; the ground connection of the device that carries the ground return current. Used in Kelvin (force/sense) configuration with GND_S to null out IR drops in ground routing. |+| 2 | GND_S | input | Ground sense pin. Analog input; connects at the load to sense the load-side ground potential, enabling force/sense (Kelvin) load regulation compensation. |+| 3 | ENABLE | input | Digital input that enables (V_H ≥ 1.5V, up to V_IN) or disables (V_L ≤ 0.7V) the reference. In shutdown, supply current drops to ~0.1µA (1µA max). May be tied to IN for input rise times ≤ 2ms. |+| 4 | IN | power_in | Positive supply voltage input. Analog input; operating range V_OUT + 0.05V (dropout) to 5.5V. Absolute maximum 7.5V. Quiescent current typ 100µA. |+| 5 | OUT_S | input | Output sense pin. Analog input; sense connection at the load used with OUT_F in a Kelvin/force-sense configuration to null out IR drops in the output trace and improve load regulation. |+| 6 | OUT_F | output | Output force pin. Analog output that sources the 2.5V reference voltage (REF3225). Delivers up to ±10mA and is stable with any capacitive load. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `REF3225AIDBVRIDBVR`+- `REF3225AIDBVRIDBVT`++## CAD (KiCad official)++- Symbol: `REF3225AIDBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/ref3225ai.pdf) (19 pp, sha256 `691719783e90148d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
