# HT7150S

**HXY MOSFET** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

HT7150S from HXY MOSFET, in a SOT-23. 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 | VIN | power_in | Unregulated input supply pin. Accepts up to 24 V typical / 30 V absolute maximum. Place an input decoupling capacitor (e.g. 10 uF) close to this pin. |
| 3 | VOUT | power_out | Regulated 5.0 V output pin (±2%), capable of sourcing up to 50 mA. Requires an output capacitor greater than 2.2 uF to ground (10 uF recommended, tantalum preferred) for loop stability via output-cap ESR compensation. |

## CAD (KiCad official)

- Symbol: `HT7150S`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ht7150s-etched.step` / `ht7150s-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ht7150s.step` / `ht7150s.glb` are the bare package body.
