TPS79633DCQR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS79633DCQR from Texas Instruments, in a SOT-223-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Enable input. Driving EN high turns the regulator on; driving EN low puts the device into shutdown mode. EN can be tied to IN if not used. Absolute-max range -0.3 V to VIN+0.3 V.
2 IN power_in Unregulated supply input to the device. Recommended operating range 2.7 V to 5.5 V. Requires a 1-uF ceramic input capacitor for stability.
3 GND power_in Regulator ground reference. Also connected to the SOT-223 tab (pin 6) for thermal dissipation.
4 OUT power_out Regulated 3.3-V output of the LDO, rated to 1 A. Requires a minimum 1-uF ceramic output capacitor for stability.
5 NR passive Noise-reduction pin. Connecting an external capacitor (typ. 0.01-0.1 uF) from NR to GND bypasses noise generated by the internal bandgap reference, improving PSRR and reducing output noise (~40 uVRMS at TPS79630 conditions). On fixed-voltage TPS79633 this pin is NR; on the adjustable TPS79601 the same pin serves as FB.
6 GND power_in SOT-223 tab, internally connected to GND. Provides the primary thermal path and should be soldered to a ground copper pour for heat dissipation.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps79633dcqr.step 120 KB You want the bare part, or you mark your own boards.
tps79633dcqr-etched.step 2.4 MB You want the part with TPS79633DCQR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 564 faces against 36 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
