TPS74012DGKT from Texas Instruments, in a VSSOP-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 | EN | input | Enable pin on the fixed output voltage version: driving it high enables the regulator, driving it low puts the regulator into shutdown, and it must not be left unconnected. |
| 2 | BIAS | power_in | Bias input voltage for the error amplifier, reference, and internal control circuits (VBIAS 2.9 V to 6.0 V per Features). |
| 3 | IN | power_in | Input to the device (VIN 1.2 V to 6.0 V per Features). |
| 4 | OUT | power_out | Regulated output voltage; a total typical capacitance of at least 2.2 µF (ceramic) to ground is needed for stability. |
| 5 | GND | power_in | Ground. |
| 6 | GND | power_in | Ground. |
| 7 | GND | power_in | Ground. |
| 8 | GND | power_in | Ground. |
