TPS73733QDRBRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VSON-8-EP(3x3)

TPS73733QDRBRQ1 from Texas Instruments, in a VSON-8-EP(3x3). 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; requires a capacitor of 1µF or larger of any type for stability, and the device is not limited by output capacitor type.
2 NC unconnected No internal connection.
3 NR passive Noise-reduction pin on the fixed-voltage version; an external capacitor CNR connected to ground bypasses the internal bandgap noise and reduces output noise to very low levels.
4 GND power_in Ground reference for the regulator.
5 EN input Enable input: driving high (above 1.7 V minimum) turns the regulator on and driving low (below 0.5 V maximum) puts it in shutdown; it must not be left floating and should be tied to IN if unused.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 IN power_in Unregulated input supply, specified from 2.2 V to 5.5 V (absolute maximum −0.3 V to 6 V).
9 GND passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS73733QDRBRQ1
  • Footprint: Package_SON:VSON-8-1EP_3x3mm_P0.65mm_EP1.6x2.4mm
  • 3D model: VSON-8-EP(3x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN 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: tps73733qdrbrq1-etched.step / tps73733qdrbrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps73733qdrbrq1.step / tps73733qdrbrq1.glb are the bare package body.
