TPS73433DDCR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS73433DDCR from Texas Instruments, in a SOT-23-5. 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 IN power_in Input supply.
2 GND power_in Ground. The pad must be tied to GND.
3 EN input Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. EN can be connected to IN if not used.
4 NR passive Fixed voltage versions only; connecting an external capacitor to this pin bypasses noise generated by the internal bandgap. This allows output noise to be reduced to very low levels.
5 OUT power_out Output of the regulator. A small capacitor (total typical capacitance ≥ 2.0µF ceramic) is needed from this pin to ground to assure stability.

CAD (KiCad official)

  • Symbol: TPS73433DDCR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tps73433ddcr-etched.step / tps73433ddcr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps73433ddcr.step / tps73433ddcr.glb are the bare package body.
