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 2.65V to 5.5V (abs max 6V). Requires a 2.2µF ceramic input capacitor to ground for stability. |+| 2 | GND | power_in | Ground reference. Ground pin (quiescent) current typically 90µA at load, <1µA in shutdown. |+| 3 | EN | input | Enable input, active high. VIH ≥ 1.2V enables the regulator; VIL ≤ 0.2V disables it (shutdown current <1µA). CMOS input - do not leave floating. |+| 4 | BYP | passive | Reference bypass. Connect an external 0.1µF ceramic capacitor from BYP to GND to reduce output noise (20µVrms) and improve PSRR. May be left open if noise performance is not critical. |+| 5 | VOUT | power_out | Regulated 1.8V output, 300mA guaranteed (600mA typical current limit). Requires a 2.2µF or greater low-ESR ceramic output capacitor to GND for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip Tech |+| Package | TSOT-23-5 |+| Category | Power Management (PMIC) |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `MIC5323-1.8YD5-TR`+- `MIC5323-1.8YD5-TR2.8YD5`+- `MIC5323-1.8YD5-TR3.3YD5`+- `MIC5323-1.8YMT`+- `MIC5323-1.8YD5-TR2.8YMT`+- `MIC5323-1.8YD5-TR3.3YMT`+- `MIC5323-1.8YD5-TRYMT`++## CAD (KiCad official)++- Symbol: `MIC5323-1.8YD5-TR`+- Footprint: `Package_TO_SOT_SMD:TSOT-23-5`+- 3D model: TSOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip Tech datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590219036551245824) (15 pp, sha256 `922a6dc4b766c454`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
