# GR7336

**GR** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

GR7336 from GR, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Chip ground terminal of the GR73xx LDO regulator. |
| 2 | VOUT | power_out | Chip output terminal, with output voltage accuracy of ±3% for the GR73xx series. |
| 3 | VIN | power_in | Startup input terminal; the datasheet gives a maximum input voltage of 18 V and a rated input voltage of 15 V. |

## CAD (KiCad official)

- Symbol: `GR7336`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3 (KiCad packages3D, STEP)
- 3D model files: `gr7336-etched.step` / `gr7336-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gr7336.step` / `gr7336.glb` are the bare package body.
