STLQ015M18R

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

STLQ015M18R from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Supply input voltage, 1.5 to 5.5 V operating range
2 GND power_in Ground reference
3 EN input Enable input, set high to turn on the device and low to turn off the device
4 NC unconnected Not connected
5 OUT output Regulated output voltage 1.8 V with ±2% accuracy at 25 °C

CAD (KiCad official)

  • Symbol: STLQ015M18R
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: stlq015m18r-etched.step / stlq015m18r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stlq015m18r.step / stlq015m18r.glb are the bare package body.

Provenance

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