# TP375C50T3

**TECH PUBLIC** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

TP375C50T3 from TECH PUBLIC, in a SOT-89-3. 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 of the regulator. |
| 2 | VIN | power_in | Power input voltage, operating range 3V to 36V (absolute maximum -0.3 to +40V); the SOT89 tab is also connected to VIN. |
| 3 | VOUT | power_out | Regulated output voltage (5.0V for the TP375C50T3), up to 200mA output current. |
