# LM340MP-5.0

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

LM340MP-5.0 from Texas Instruments, 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 | INPUT | power_in | Input voltage pin; accepts DC input voltage up to 35V absolute maximum. |
| 2 | GND | power_in | Ground pin; establishes return reference potential for the regulator. |
| 3 | OUTPUT | power_out | Output voltage pin; provides regulated 5V output with maximum 1.5A output current. |
