RT9013-18GB

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

RT9013-18GB from Richtek Tech, 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 Supply input. Operating range 2.2 V to 5.5 V (6 V absolute max). Bypass with a 1 uF ceramic (X7R) capacitor to GND close to the pin for stability.
2 GND power_in Common ground return for the regulator. Serves as the reference for VOUT and EN thresholds.
3 EN input Enable input, active high. VIH >= 1.6 V turns the regulator on; VIL <= 0.6 V (or EN = 0 V) puts the device in shutdown (typ 0.7 uA). Do not leave floating; tie high or drive with a logic signal. Absolute max 6 V.
4 NC unconnected No internal connection. May be left floating or tied to GND.
5 VOUT power_out Regulated output. Fixed 1.8 V for RT9013-18 option, +/-2% accuracy at 10 mA load, 500 mA maximum. Requires only a 1 uF ceramic (X7R) output capacitor for stability.

CAD (KiCad official)

  • Symbol: RT9013-18GB
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: rt9013-18gb-etched.step / rt9013-18gb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rt9013-18gb.step / rt9013-18gb.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
rt9013-18gb.step 85 KB You want the bare part, or you mark your own boards.
rt9013-18gb-etched.step 2.2 MB You want the part with RT9013-18GB already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 539 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
