TPS78512QKVURQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-4

TPS78512QKVURQ1 from Texas Instruments, in a TO-252-4. 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 EN input Enable pin controlled by logic signal to enable (high) or disable (low) the device; must not be left floating.
2 IN power_in Input power supply pin accepting 1.7V to 6.0V; place ≥1.0µF ceramic capacitor from IN to GND as close to pin as possible.
3 GND power_in Ground reference pin; must be connected to board ground and thermal plane for performance.
4 OUT power_out Regulated 1.2V output pin delivering up to 1A; requires ≥0.47µF capacitance to ground for stability, ≥1µF ceramic capacitor recommended.
5 NC unconnected No-connect pin internally unconnected; connect to ground for improved thermal performance or leave floating.

  • Symbol: TPS78512QKVURQ1
  • Footprint: Package_TO_SOT_SMD:TO-252-4
  • 3D model: TO-252-4 (KiCad packages3D, STEP)
  • Annotated 3D hero: tps78512qkvurq1-hero.glb (dashed pad outlines, silkscreen with pin 1, signal names; the adom-hero standard) is what the viewer shows. Downloads and EDA use the clean model, tps78512qkvurq1-etched.glb.
  • 3D model files: tps78512qkvurq1-etched.step / tps78512qkvurq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps78512qkvurq1.step / tps78512qkvurq1.glb are the bare package body.
