MC78LC33NTRG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOT-23-5

MC78LC33NTRG from onsemi, in a TSOT-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 GND power_in Power supply ground / device common return.
2 Vin power_in Positive power supply input voltage. Absolute max 12 V; typical operation Vin = Vout(nom) + 1.0 V up to 12 V.
3 Vout power_out Regulated 3.3 V output (3.234 V to 3.366 V at TA=25°C, Iout=1 mA). Requires a minimum 0.1 µF ceramic output capacitor for stability. Output current capability 50 mA min (Vin = 6.0 V).
4 N/C unconnected No internal connection. Leave floating or tie to any convenient net.
5 N/C unconnected No internal connection. Leave floating or tie to any convenient net.

CAD (KiCad official)

  • Symbol: MC78LC33NTRG
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: TSOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: mc78lc33ntrg-etched.step / mc78lc33ntrg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc78lc33ntrg.step / mc78lc33ntrg.glb are the bare package body.

Provenance

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

  • Datasheet: onsemi datasheet (12 pp, sha256 0ffc84c69bbb9fb1, retrieved 2026-08-17, tier: manufacturer)
  • 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).
