# AMS1117MDT-1.8RG

**HANSCHIP semiconductor** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2L

AMS1117MDT-1.8RG from HANSCHIP semiconductor, in a TO-252-2L. 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/ADJ | power_in | Ground pin (ADJ on the adjustable version); on this fixed 1.8V part it is the ground reference. |
| 2 | VOUT | power_out | Regulated output voltage pin (1.8V for this fixed version); the drawing shows pin 2 as a short or absent lead. |
| 3 | VIN | power_in | Input operating voltage pin. |

## CAD (KiCad official)

- Symbol: `AMS1117MDT-1.8RG`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252-2L (KiCad packages3D, STEP)
- 3D model files: `ams1117mdt-1-8rg-etched.step` / `ams1117mdt-1-8rg-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ams1117mdt-1-8rg.step` / `ams1117mdt-1-8rg.glb` are the bare package body.
