Internally compared to the 1.25 V bandgap reference; drive from the tap of the external R1/R2 divider between K and A to program V_KA = V_REF·(1 + R1/R2) + I_REF·R1. Input bias current I_REF ≈ 0.15 µA typ (0.4 µA max) at I_KA = 10 mA. |+| 2 | A | power_in | Anode. Return terminal of the shunt regulator; connected to ground/low side in typical bias applications. Sinks the cathode current back to the supply return. |+| 3 | K | power_in | Cathode. High-side terminal of the shunt regulator; typically tied through a pull-up resistor from the rail (V_KA up to 18 V, absolute max 20 V). Regulates V_KA to the programmed voltage as it sinks 70 µA-100 mA. Dynamic impedance |Z_KA| ≈ 0.05 Ω typ at 1 kHz. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `ME432AXG`+- `ME432AXGME432BXG`+- `ME432AXGME432ATG`+- `ME432AXGME432BTG`+- `ME432AXGME432ATBG`+- `ME432AXGME432BTBG`+- `ME432AXGME432NAXG`+- `ME432AXGME432NBXG`++## CAD (KiCad official)++- Symbol: `ME432AXG`+- 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:** [MICRONE datasheet](docs/me432axg-datasheet.pdf) (11 pp, sha256 `c3419ca376cad158`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
