**MST** · Linear Voltage Regulators (LDO) · SOT-23

MST5350BTE from MST, in a SOT-23. 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 | power_in | Ground pin, the reference for the VIN Pin to GND Pin rating of -0.3 to 35 V and the VOUT Pin to GND Pin rating of -0.3 to 6 V. |
| 2 | VOUT | power_out | Regulated output pin delivering up to 200mA with a fixed output voltage, with a VOUT Pin to VIN Pin range of -35 to 0.3 V. |
| 3 | VIN | power_in | Input supply pin that accepts voltages as high as 35V, with a VIN Pin to GND Pin range of -0.3 to 35 V. |
