TPS7A4901DGNR

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

TPS7A4901DGNR 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 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.

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). 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: tps7a4901dgnr-etched.step / tps7a4901dgnr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps7a4901dgnr.step / tps7a4901dgnr.glb are the bare package body.
