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 | ANODE | power_in | Anode terminal - the reference/return node for the shunt regulator. All specified voltages (VKA, VREF) are measured relative to this pin. Typically tied to the low-side rail (system ground) in a shunt-regulator topology. |+| 2 | REF | input | Reference input to the internal error amplifier. The device servos the cathode current so that V(REF)-V(ANODE) equals the internal bandgap reference (2.495V typ). Reference input current is 1µA typ (4µA max); tie directly to CATHODE for VKA = VREF, or to the tap of an R1/R2 divider from CATHODE to ANODE to program VOUT = (1 + R1/R2)·VREF up to 36V. |+| 3 | CATHODE | power_in | Cathode terminal - the regulated shunt node that sinks current from the supply through a series resistor to hold the programmed voltage. Rated VKA up to 40V absolute max (36V recommended), IKA 0.065mA to 100mA operating (150mA absolute max). Dynamic output impedance is 0.2Ω typ; off-state leakage is 0.05µA typ at VKA = 36V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `ZXRE252ASA-7`+- `ZXRE252ASA-7ZXRE252BSA-7`+- `ZXRE252ASA-7ZXRE250ASA-7`+- `ZXRE252ASA-7ZXRE250BSA-7`+- `ZXRE252ASA-7ZXRE250AW5-7`+- `ZXRE252ASA-7ZXRE250BW5-7`++## CAD (KiCad official)++- Symbol: `ZXRE252ASA-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/zxre252asa-7-datasheet.pdf) (None pp, sha256 `8cc0985319ab55ca`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
