TPS7A3001DGNR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · HVSSOP-8

TPS7A3001DGNR 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 Regulator output; a capacitor ≥ 2.2 µF must be tied from this pin to ground to ensure stability.
2 FB input Feedback pin that sets the output voltage of the device.
3 NC unconnected Not internally connected; this pin must either be left open or tied to GND.
4 GND power_in Ground.
5 EN input Enable pin that turns the regulator on or off; regulator is enabled if VEN ≥ VEN(+HI,min) or VEN ≤ VEN(-HI,max), and disabled if VEN(+LO,max) ≥ VEN ≥ VEN(-LO,min); can be tied to IN if unused, with
6 NR/SS passive Noise-reduction/soft-start pin; an external capacitor connected here filters internal band-gap noise to reduce output RMS noise and also programs the soft-start ramp time.
7 DNC unconnected Do not connect; do not route this pin to any electrical net, not even GND or IN.
8 IN power_in Input supply, -3 V to -35 V.
9 PowerPAD power_in Exposed thermal pad; must either be left open or tied to GND, and should be soldered to a PCB ground plane to enhance thermal performance.

CAD (KiCad official)

  • Symbol: TPS7A3001DGNR
  • 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: tps7a3001dgnr-etched.step / tps7a3001dgnr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps7a3001dgnr.step / tps7a3001dgnr.glb are the bare package body.
