# TPS2065DGNR-1

**Texas Instruments** · Power Distribution Switches · MSOP-8

TPS2065DGNR-1 from Texas Instruments, in a MSOP-8. 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 connection for the device. |
| 2 | IN | power_in | Input voltage, operating range 2.7 V to 5.5 V; connect a 0.1 µF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 3 | IN | power_in | Input voltage, operating range 2.7 V to 5.5 V; connect a 0.1 µF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 4 | EN | input | Enable input, logic high turns on the power switch; recommended input range is 0 V to 5.5 V. |
| 5 | OC | output | Active-low open-drain output, asserted during over-current. |
| 6 | OUT | power_out | Power-switch output; continuous output current is 0 to 1 A (internally limited). |
| 7 | OUT | power_out | Power-switch output; continuous output current is 0 to 1 A (internally limited). |
| 8 | OUT | power_out | Power-switch output; continuous output current is 0 to 1 A (internally limited). |
