Delivers the inverted supply, approximately -(V+), up to 25 mA. Connect the output charge-storage/reservoir capacitor C2 (typ. 10 µF, low ESR, 0.3 Ω max) from this pin to GND. |+| 2 | V+ | power_in | Power supply positive input. Operating range 1.8 V to 5.5 V (absolute max 5.8 V to GND). Bypass locally to GND. |+| 3 | CAP- | passive | Charge-pump flying-capacitor negative terminal. Connect to the negative terminal of the pump capacitor C1 (typ. 10 µF, low ESR). Switched between GND and OUT internally. |+| 4 | GND | power_in | Power supply ground input. Reference for both V+ and OUT. |+| 5 | CAP+ | passive | Charge-pump flying-capacitor positive terminal. Connect to the positive terminal of the pump capacitor C1 (typ. 10 µF, low ESR). Switched between V+ and GND internally at ~12 kHz. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Power Management (PMIC) |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `LM828M5X`++## CAD (KiCad official)++- Symbol: `LM828M5X`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lm828) (17 pp, sha256 `e2f4d81a8e4e5b4f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
