# LR6207A-T50

**LR** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

LR6207A-T50 from LR, in a SOT-23-5L. 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 | Unregulated input supply. Operating range up to 6.5V (typ), absolute maximum 9V. Bypass to VSS with a ~1uF capacitor close to the pin. |
| 2 | VSS | power_in | Device ground / negative supply reference. All voltage measurements are referenced to VSS. |
| 3 | CE | input | Chip Enable (active-high). Enables the regulator when driven above VCE(H) (min 0.7V at VIN=2.2V); disables (shutdown) when below VCE(L) (max 1.2V logic threshold specified for turn-on). Do not leave floating. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to VSS for mechanical stability. |
| 5 | VOUT | power_out | Regulated 5.0V output (±2% accuracy). Requires an output capacitor (typ. 1uF) to VSS for stability. Rated to 300mA typical, 450mA absolute-maximum output current; internally short-circuit protected (~25mA short-circuit current). |

## CAD (KiCad official)

- Symbol: `LR6207A-T50`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5L (KiCad packages3D, STEP)
- 3D model files: `lr6207a-t50-etched.step` / `lr6207a-t50-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lr6207a-t50.step` / `lr6207a-t50.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`lr6207a-t50.step`](lr6207a-t50.step) | 85 KB | You want the bare part, or you mark your own boards. |
| [`lr6207a-t50-etched.step`](lr6207a-t50-etched.step) | 1.9 MB | You want the part with `LR6207A-T50` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 469 faces against 102 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.
