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 | power_out | Regulator output; a capacitor of at least 2.2 µF must be tied from this pin to ground to ensure stability. |+| 2 | FB | input | Input to the error amplifier; FB is used to set the output voltage of the device. |+| 3 | NC | unconnected | Not internally connected; this pin can either be left open or tied to GND. |+| 4 | GND | power_in | Ground connection for the device. |+| 5 | EN | input | Enable pin that turns the regulator on when VEN ≥ VEN(high) and off when VEN ≤ VEN(low); can be tied to IN if not used, and VEN must not exceed VIN. |+| 6 | NR/SS | passive | Noise-reduction/soft-start pin; an external capacitor connected here bypasses internal band-gap noise, reducing RMS output noise and setting the soft-start time. |+| 7 | DNC | unconnected | Do not connect; this pin must not be routed to any electrical net, including GND or IN. |+| 8 | IN | power_in | Input supply pin for the regulator. |+| 9 | PowerPAD | power_in | Exposed thermal pad; must either be left open or tied to ground, and should be soldered to the PCB ground plane to enhance thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | HVSSOP-8 |+| Category | Power Management (PMIC) |+| Pins | 9 |++## CAD (KiCad official)++- Symbol: `TPS7A4901DGNR`+- Footprint: `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).
