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 | Supply input. Operating range 2.5V to 5.5V (absolute max 6V). Bypass with a 1µF ceramic capacitor to GND. |+| 2 | GND | power_in | Ground return for the regulator. Carries the load return and the ~38-65µA quiescent current. |+| 3 | EN | input | Enable input, active high (High = ON, Low = OFF). VIH ≥ 1.2V, VIL ≤ 0.2V. MIC5504 has an internal ~4MΩ pull-down so the pin may be left floating (defaults off). Absolute max −0.3V to VIN. |+| 4 | NC | unconnected | No Connection. Pin is not internally connected; may be left floating or tied to GND. |+| 5 | VOUT | power_out | Regulated 3.3V output, 300mA guaranteed. When disabled, the MIC5504 auto-discharge circuit switches an internal ~25Ω load across VOUT to discharge external capacitors. Requires ≥1µF ceramic output capacitor for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `MIC5504-3.3YM5-TR3.3YM5`+- `MIC5504-3.3YM5-TR2.8YM5`+- `MIC5504-3.3YM5-TR2.5YM5`+- `MIC5504-3.3YM5-TR1.8YM5`+- `MIC5504-3.3YM5-TR1.2YM5`+- `MIC5504-3.3YM5-TR3.3YMT`+- `MIC5504-3.3YM5-TR3.1YMT`+- `MIC5504-3.3YM5-TR3.0YMT`+- `MIC5504-3.3YM5-TR2.8YMT`+- `MIC5504-3.3YM5-TR2.5YMT`+- `MIC5504-3.3YM5-TR2.2YMT`+- `MIC5504-3.3YM5-TR1.8YMT`+- `MIC5504-3.3YM5-TR1.2YMT`++## CAD (KiCad official)++- Symbol: `MIC5504-3.3YM5-TR`+- 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:** [Microchip datasheet](docs/mic5504-3-3ym5-tr-datasheet.pdf) (15 pp, sha256 `ecd89dfc7e29efd0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
