# GR7336-A

**GR** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

GR7336-A from GR, in a SOT-89-3. 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 (芯片接地端) for the GR73xx LDO regulator in the SOT89-3 package. |
| 2 | VIN | power_in | Start-up/input terminal (启动输入端); the datasheet rates the input voltage up to 15 V, with an absolute maximum input voltage of 18 V. |
| 3 | VOUT | power_out | Chip output terminal (芯片输出端) providing the regulated output voltage, which is 3.6 V with ±3% tolerance for GR7336-A. |

## CAD (KiCad official)

- Symbol: `GR7336-A`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89-3 (KiCad packages3D, STEP)
- 3D model files: `gr7336-a-etched.step` / `gr7336-a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gr7336-a.step` / `gr7336-a.glb` are the bare package body.
