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 | power_in | Power supply ground input. Return for the positive supply V+ and the charge-pump switching stage. |+| 2 | OUT | power_out | Negative voltage output. Produces -V+ (down to -5.5 V) with up to 40 mA load current; requires an external reservoir capacitor (typ. 3.3 uF, <=0.3 ohm ESR) to GND. |+| 3 | CAP- | passive | Negative terminal of the external flying (charge-pump) capacitor (typ. 3.3 uF, <=0.3 ohm ESR). Switched between V+ and OUT internally at fSW ~80 kHz. |+| 4 | SD | input | Shutdown control input. Tie to V+ (VIH >= 40% of V+, min 2 V) for normal operation; tie to GND (VIL <= 20% of V+, max 0.8 V) to enter shutdown (ISD ~1 uA). Absolute range GND-0.3 V to V++0.3 V. |+| 5 | V+ | power_in | Positive supply input, 1.8 V to 5.5 V (absolute max 5.8 V). Quiescent current ~220 uA typical (500 uA max) with no load. |+| 6 | CAP+ | passive | Positive terminal of the external flying (charge-pump) capacitor (typ. 3.3 uF, <=0.3 ohm ESR). Switched between V+ and GND internally. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `LM2664M6XM6X`+- `LM2664M6XM6`++## CAD (KiCad official)++- Symbol: `LM2664M6X`+- 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/lm2664m6x.pdf) (20 pp, sha256 `49d43b3879282bf8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
