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 | VCC | power_in | Input supply. Operating range 2.7 V to 5.5 V; absolute maximum 6 V. Powers the internal sequencer logic and reference. |+| 2 | GND | power_in | Ground reference for the device (0 V). Connect to the system ground plane. |+| 3 | EN | input | Precision enable input. Rising edge above VEN (typ. 1.25 V, range 1.0-1.4 V) initiates the power-up sequence; a falling edge below the threshold triggers the reverse power-down sequence. Input current ~7 μA at VEN = 0 V. Absolute maximum -0.3 V to 6 V. |+| 4 | FLAG3 | output | Open-drain enable output 3 (third to assert on power-up, first to de-assert on power-down). Requires external pull-up; may be pulled to a rail higher than VCC (up to 6 V absolute max) to interface with higher-voltage enable pins. Sink capability up to 1.2 mA at VOL ≤ 0.4 V; leakage ~1 nA (max 20 nA) when off. |+| 5 | FLAG2 | output | Open-drain enable output 2 (second to assert on power-up, second to de-assert on power-down). Requires external pull-up; may be pulled to a rail higher than VCC (up to 6 V absolute max). Sink capability up to 1.2 mA at VOL ≤ 0.4 V; leakage ~1 nA (max 20 nA) when off. |+| 6 | FLAG1 | output | Open-drain enable output 1 (first to assert on power-up, last to de-assert on power-down). Requires external pull-up; may be pulled to a rail higher than VCC (up to 6 V absolute max). Sink capability up to 1.2 mA at VOL ≤ 0.4 V; leakage ~1 nA (max 20 nA) when off. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `LM3880MF-1AB`++## CAD (KiCad official)++- Symbol: `LM3880MF-1AB`+- 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/cn/lit/gpn/lm3880) (30 pp, sha256 `d06a410f635eefab`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
