TPMIC5233-3.3YM5

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPMIC5233-3.3YM5 from TECH PUBLIC, 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 VIN power_in Input supply voltage. Operating range 3.5V to 36V (absolute max 40V). Requires a 1µF ceramic input capacitor (CIN) to GND.
2 GND power_in Ground reference for the regulator. Common return for VIN, VOUT, and EN.
3 EN input Enable control input. Drive high (VIH ≥ 2V) to enable the regulator; drive low (VIL ≤ 0.6V) to shut down (ISD typ 0.01µA). EN input current typ 10nA at VEN = 36V. Do not float.
4 NC unconnected No internal connection. Leave floating or tie to any convenient net; not electrically connected to the die.
5 VOUT power_out Regulated output of the LDO. Fixed 3.3V ±2%, up to 200mA output current (300mA typ current limit). Requires an output capacitor with effective capacitance ≥ 1µF (ceramic or tantalum) for stability. Dropout typ 0.75V at IOUT = 100mA for VOUT = 3.3V.

Two STEP files. Same geometry, different body top:

File Size Use it when
tpmic5233-3-3ym5.step 85 KB You want the bare part, or you mark your own boards.
tpmic5233-3-3ym5-etched.step 2.8 MB You want the part with TPMIC5233-3.3YM5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 673 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.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (9 pp, sha256 9c824acda7bc749e, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
