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 | VIN | power_in | Device input supply. Operating range 1.5 V to 5.5 V (absolute max −6 V to 6 V). Source terminal of the internal P-channel MOSFET; input current up to 1.5 A continuous. |+| 2 | GND | power_in | Device ground reference. |+| 3 | ~{CE} | input | Active-low chip enable input (comparator). Voltage range 0 V to 5.5 V. Can be tied to VOUT for automatic reverse-current protection (ORing). Do not leave floating. Turn-ON threshold VCE−VIN ≈ −150 mV, turn-OFF ≈ +35 mV. |+| 4 | NC | unconnected | Not internally connected. May be tied to GND or left floating. |+| 5 | ST | output | Active-low open-drain status output. Pulled low when the chip is disabled (MOSFET off); Hi-Z when enabled. Voltage range 0 V to 5.5 V; VOL ≈ 0.1 V at IST = 1 mA. Connect to GND if not required. |+| 6 | VOUT | power_out | Device output. Drain of the internal P-channel MOSFET. Output voltage range 1 V to 5.5 V; supports up to 1.5 A continuous output current. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `LM66100DCKRDCKR`+- `LM66100DCKRDCKT`++## CAD (KiCad official)++- Symbol: `LM66100DCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC-70-6 (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/lm66100.pdf) (23 pp, sha256 `83c17370a97b85ec`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
