# MCP1702T-3302E/CB

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

MCP1702T-3302E from Microchip, in a SOT-23A-3. 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 reference for the regulator. Connect directly to the system ground plane. |
| 2 | VOUT | power_out | Regulated output voltage pin, nominal 3.3V for the -3302 option. Delivers up to 250 mA (VR ≥ 2.5V). Requires a 1 µF (min) to 22 µF ceramic, tantalum, or aluminum electrolytic output capacitor for stability. |
| 3 | VIN | power_in | Unregulated supply input. Operating range 2.7V to 13.2V; absolute maximum 14.5V. Requires VIN ≥ VOUT(MAX) + VDROPOUT(MAX). A 1 µF ceramic input capacitor is recommended. |

## CAD (KiCad official)

- Symbol: `MCP1702T-3302E`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23A-3 (KiCad packages3D, STEP)
- 3D model files: `mcp1702t-3302e-etched.step` / `mcp1702t-3302e-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mcp1702t-3302e.step` / `mcp1702t-3302e.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`mcp1702t-3302e.step`](mcp1702t-3302e.step) | 59 KB | You want the bare part, or you mark your own boards. |
| [`mcp1702t-3302e-etched.step`](mcp1702t-3302e-etched.step) | 2.4 MB | You want the part with `MCP1702T-3302E` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 571 faces against 69 in the bare model. It
survives export, section views, and rendering in any CAD tool, and it drops straight
into KiCad or Fusion with no extra setup.
