TPS7A0218PDBVR

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

TPS7A0218PDBVR from Texas Instruments, in a SOT-23-5. 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 IN power_in Input supply pin, 1.5 V to 6.0 V. Bypass with a 1 µF (or larger) ceramic capacitor from IN to GND placed as close to the pin as possible for best transient response and minimum input impedance.
2 GND power_in Device ground. Must be connected to the board ground.
3 EN input Active-high enable input (V_EN(HI) ≥ 1.1 V, V_EN(LOW) ≤ 0.3 V). Driving high enables the LDO; driving low or floating disables it. Contains an internal ~500 kΩ smart pulldown that is disconnected once EN is driven high and the device has started, minimizing static current.
4 NC unconnected No internal connection. Tie to ground or leave floating.
5 OUT power_out Regulated output, 1.8 V nominal, up to 200 mA. Requires an effective ceramic capacitance of at least 0.5 µF (1 µF typical, up to 22 µF derated) from OUT to GND for stability; place as close to the pin as possible for best transient response.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps7a0218pdbvr.step 85 KB You want the bare part, or you mark your own boards.
tps7a0218pdbvr-etched.step 2.5 MB You want the part with TPS7A0218PDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 607 faces against 102 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.
