TPLP5907MFX-3.3

TECH PUBLIC TPLP5907MFX 3 3 · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPLP5907MFX-3.3 from TECH PUBLIC TPLP5907MFX 3 3, in a SOT-23-5. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply voltage. Accepts 1.2V to 5.5V; absolute maximum -0.3V to 6.5V referenced to GND. Bypass to GND with a 1µF ceramic or tantalum capacitor placed close to the pin.
2 GND power_in Device ground. Serves as the return for VIN, VOUT, and the internal reference. Typical ground (quiescent) current is 2µA at no load.
3 EN input Enable control input. Logic-high (VENH ≥ 0.5V typ 0.7V) turns the regulator on; logic-low (VENL ≤ 0.85V max, with typ threshold 0.65V) shuts it down to ~0.1µA. When disabled, VOUT is actively discharged through an internal ~80Ω resistor. Absolute maximum -0.3V to 6.5V; do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND for improved thermal/mechanical stability on the PCB.
5 VOUT power_out Regulated output of the LDO. Fixed 3.3V ±2% at up to 300mA. Requires a minimum 1µF ceramic or tantalum output capacitor to GND for loop stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
tplp5907mfx-3-3.step 85 KB You want the bare part, or you mark your own boards.
tplp5907mfx-3-3-etched.step 2.3 MB You want the part with TPLP5907MFX-3.3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 567 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:
