TC1262-3.3VDBTR

Microchip · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

TC1262-3.3VDBTR from Microchip, in a SOT-223. 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 VIN power_in Unregulated input supply. Operating range 2.7 V to 6.0 V (absolute max 6.5 V). A 1 µF input capacitor is recommended when the source impedance is high or lead length exceeds 10 inches.
2 GND power_in Ground return. The SOT-223 tab is also GND and should be soldered to the top-layer copper for improved thermal dissipation (θJA as low as 45 °C/W with 2500 sq mm copper).
3 VOUT power_out Regulated 3.3 V output (factory-trimmed, ±0.5% typical, ±2.5% max). Requires at least a 1 µF capacitor to GND with ESR between 0.1 Ω and 5.0 Ω and self-resonance above 1 MHz for stability. Maximum output current 500 mA; internal current-limit typically 1.2 A; short-circuit and thermal-shutdown protected.

CAD (KiCad official)

  • Symbol: TC1262-3.3VDBTR
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: tc1262-3-3vdbtr-etched.step / tc1262-3-3vdbtr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tc1262-3-3vdbtr.step / tc1262-3-3vdbtr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tc1262-3-3vdbtr.step 64 KB You want the bare part, or you mark your own boards.
tc1262-3-3vdbtr-etched.step 2.5 MB You want the part with TC1262-3.3VDBTR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 611 faces against 75 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: Microchip datasheet (12 pp, sha256 f6fea66a57b90fb7, retrieved 2026-08-17, tier: manufacturer)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
