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 | GND | power_in | Ground / VSS reference for the regulator. Connect to system ground; the 1uF ceramic input and output bypass capacitors return here. |+| 2 | VOUT | power_out | Regulated 3.3V output (tolerance +/-2%, Vout x 0.98 to Vout x 1.02). Rated 300mA (limited by package power dissipation, Pd = 0.20W for SOT23-3). Requires >=1uF low-ESR ceramic output capacitor for stability. |+| 3 | VIN | power_in | Unregulated supply input. Operating range typ 6V, absolute max 10V; recommended Vin = Vout + 1V for regulation (dropout ~0.19V typ / 0.35V max at 100mA for Vout >= 2.8V). Bypass with 1uF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `H7605-33MRMR`+- `H7605-33MRMG`+- `H7605-33MRNR`+- `H7605-33MRNG`+- `H7605-33MRPR`+- `H7605-33MRPG`++## CAD (KiCad official)++- Symbol: `H7605-33MR`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shanghai Siproin Microelectronics datasheet](docs/h7605-33mr-datasheet.pdf) (6 pp, sha256 `363a66b804bb6b8a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
