LTR3330T20YT3

Guestgood · Voltage Reference · SOT-23-3

LTR3330T20YT3 from Guestgood, in a SOT-23-3. 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 Power supply voltage input. Operates from 2.7 V to 5.5 V (must be at least VOUT + 0.2 V for regulation). A 1 µF low-ESR ceramic bypass capacitor (CBYPASS, 1 µF to 10 µF recommended) should be placed close to this pin.
2 REF power_out Reference voltage output (3.0 V nominal for LTR3330). Requires an external ceramic capacitor CL of 0.1 µF to 10 µF for stability. Sources/sinks up to ±5 mA (short-circuit current typ 50 mA).
3 GND power_in Ground reference. Connect to a solid ground plane via a low-impedance path to minimize noise pickup and thermally-induced (Seebeck) errors.

Provenance

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

  • Datasheet: Guestgood datasheet (None pp, sha256 24e1b1538e63cb5e, retrieved 2026-08-17, tier: lcsc)
  • 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).
