# LM341T-5.0

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

LM341T-5.0 from Texas Instruments, in a TO-220-3. 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 | INPUT | power_in | Unregulated input supply; the Recommended Operating Conditions give an input voltage of VOUT + 1.8 V to 35 V, and the absolute maximum input voltage is 35 V. |
| 2 | GND | power_in | Ground reference for the regulator; the datasheet lists this pin as GND/TAB and states the tab is also GND. |
| 3 | OUTPUT | power_out | Regulated 5 V output that sources up to the 0.5 A recommended output current. |
