# MIC5200-3.3YS

**UMW** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

MIC5200-3.3YS from UMW, in a SOT-223. 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 | IN | power_in | Supply input; the recommended input voltage range is 2.5V to 26V, and the input absolute maximum is -20V to +60V. |
| 2 | GND | power_in | Ground pin, internally connected to the TAB. |
| 3 | OUT | power_out | Regulated output; the datasheet notes that connecting it to a ground plane gives the lowest thermal resistance. |

## CAD (KiCad official)

- Symbol: `MIC5200-3.3YS`
- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`
- 3D model: SOT-223 (KiCad packages3D, STEP)
- 3D model files: `mic5200-3-3ys-etched.step` / `mic5200-3-3ys-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mic5200-3-3ys.step` / `mic5200-3-3ys.glb` are the bare package body.
