# TPS7A6650QDGNRQ1

**Texas Instruments** · Linear Voltage Regulators (LDO) · HVSSOP-8

TPS7A6650QDGNRQ1 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 | VIN | power_in | Unregulated input power-supply voltage; 4V to 40V operating range, maximum 45V. |
| 2 | EN | input | Enable input; device enters standby when EN voltage falls below enable threshold. |
| 3 | NC | unconnected | No internal connection. |
| 4 | CT | output | Reset-pulse delay adjustment; connect capacitor from this pin to GND to set PG reset pulse delay. |
| 5 | GND | power_in | Ground reference. |
| 6 | PG | output | Power-good open-drain output; high when VOUT is above power-on-reset threshold. |
| 7 | FB/DNC | input | Feedback input for external resistor divider in adjustable output mode, or DNC (do not connect) in fixed output mode. |
| 8 | VOUT | output | Regulated output voltage; 1.5V to 5.5V operating range. |
| 9 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TPS7A6650QDGNRQ1`
- 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). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `tps7a6650qdgnrq1-etched.step` / `tps7a6650qdgnrq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps7a6650qdgnrq1.step` / `tps7a6650qdgnrq1.glb` are the bare package body.
