Reverse-biased across an external current-limiting resistor; regulates to ~1.235 V with 10 µA-20 mA reverse current. |+| 2 | - | passive | Anode (negative / ground-side terminal) of the band-gap reference diode. |+| 3 | DAP | passive | Die Attach Pad. Per the connection diagram note, pin 3 should be connected to pin 2 (Anode) or left floating; it is not a functional signal terminal. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments LM385M3X 1 2 NOPB |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LM385M3X-1.2M3X`+- `LM385M3X-1.2M3`+- `LM385M3X-1.2M`+- `LM385M3X-1.2LP`+- `LM385M3X-1.2LPR`+- `LM385M3X-1.2LPX`+- `LM385M3X-1.2LPRX`+- `LM385M3X-1.2H`++## CAD (KiCad official)++- Symbol: `LM385M3X-1.2`+- 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:** [Texas Instruments LM385M3X 1 2 NOPB datasheet](https://www.ti.com/lit/ds/symlink/lm385m3x-1.2.pdf) (28 pp, sha256 `733089279fec1712`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
