# TP2028-3.0YN5G

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

TP2028-3.0YN5G from TECH PUBLIC, in a SOT-23-5. 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 | Supply power input. Accepts up to 7V absolute max; typical operation Vout+1V to 8V. Bypass with 1uF ceramic to GND. |
| 2 | GND | power_in | Device ground reference and return path. |
| 3 | CE | input | Chip Enable / shutdown control input. Drive high (>=1.1V) to enable the regulator; drive to 0V to enter standby (ICEL <=1uA). |
| 4 | NC | unconnected | No internal connection. Leave floating or tie as recommended by layout. |
| 5 | VOUT | power_out | Regulated 3.0V output, 500mA typical capability with +/-2% accuracy. Requires 1uF ceramic output capacitor to GND for stability. |

## CAD (KiCad official)

- Symbol: `TP2028-3.0YN5G`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tp2028-3-0yn5g-etched.step` / `tp2028-3-0yn5g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tp2028-3-0yn5g.step` / `tp2028-3-0yn5g.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`tp2028-3-0yn5g.step`](tp2028-3-0yn5g.step) | 85 KB | You want the bare part, or you mark your own boards. |
| [`tp2028-3-0yn5g-etched.step`](tp2028-3-0yn5g-etched.step) | 2.6 MB | You want the part with `TP2028-3.0YN5G` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 616 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.
