TPS7A7002DDAR

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

TPS7A7002DDAR from Texas Instruments, in a SOIC-8-EP. 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 NC unconnected Not internally connected. TI recommends connecting NC pins to large-area planes.
2 EN input Enable input. Pulling this pin to less than 0.5 V turns the regulator off; pulling it to at least 1.1 V enables it. Connect to VIN if not being used. VEN range 0 V to VIN; IEN typ 0.2 µA max.
3 IN power_in Input supply pin, 1.425 V to 6.5 V. Although not required for stability, TI recommends a 1-µF to 10-µF low-ESR capacitor from IN to GND.
4 NC unconnected Not internally connected. TI recommends connecting NC pins to large-area planes.
5 NC unconnected Not internally connected. TI recommends connecting NC pins to large-area planes.
6 OUT power_out Regulated output, adjustable from 0.5 V, supplying up to 3 A. A 4.7-µF or larger capacitor of any type is required for stability (4.7 µF to 200 µF recommended range).
7 FB input Output-voltage feedback input. Connect to the tap of an external R1/R2 divider from OUT to GND; VOUT = 0.5 × (1 + R1/R2). VREF nominal 0.5 V; IFB max 1 µA. Use 27-kΩ ≤ R2 ≤ 33-kΩ when setting VOUT above 0.5 V.
8 GND power_in Ground reference pin. IGND typical 3 mA (VIN = 3.3 V, 50-Ω load); shutdown IGND max 5 µA.
9 PowerPAD passive Exposed thermal pad on the package underside. TI strongly recommends connecting to a large-area ground plane; may alternatively connect to an electrically floating dedicated thermal plane. Required for the specified 46.4 °C/W RθJA thermal performance.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps7a7002ddar.step 125 KB You want the bare part, or you mark your own boards.
tps7a7002ddar-etched.step 2.4 MB You want the part with TPS7A7002DDAR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 605 faces against 152 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (21 pp, sha256 c599367c7bc6a7fc, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
