TPS79850QDGNRQ1 from Texas Instruments, in a HVSSOP-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 | OUT | output | Regulated output voltage pin. A small (1μF) capacitor is needed from this pin to ground to provide stability. |
| 2 | SENSE/FB | input | This pin is the input to the control loop error amplifier. Use this pin to set the output voltage of the device. |
| 3 | NC | unconnected | No internal connection. |
| 4 | GND | power_in | Ground. The exposed thermal pad is connected to ground through this pin. |
| 5 | EN | input | Enable pin. Driving the EN pin high turns on the regulator over full operating range. Driving this pin low puts the regulator into shutdown mode over full operating range. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | IN | input | Input pin. Place a 0.1μF ceramic or greater capacitor from this pin to ground to provide stability. Both input and output capacitor grounds must be tied back to the device ground with no significant impedance between them. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Package_SO:HVSSOP-8-1EP_3x3mm_P0.65mm_EP1.57x1.89mm - 3D model: HVSSOP-8, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal HVSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
