RS3236-3.3YF5

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

RS3236-3.3YF5 from Jiangsu RUNIC 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 IN power_in Regulator input supply. Accepts 1.7 V to 7.5 V (absolute max 8 V). Bypass to GND with a 1 µF ceramic capacitor placed close to the pin.
2 GND power_in Device ground reference. All voltages are referenced to this pin. Typical ground pin current is 15 µA (20 µA max) at no load.
3 EN input Enable input. Driving EN logic low (<0.4 V at VIN=1.7 V, <0.8 V at VIN=7.5 V) shuts the regulator down and reduces supply current to ~10 nA. VIH ≥1.4 V at VIN=1.7 V (≥2.3 V at VIN=7.5 V) enables the regulator. Tie to IN for always-on operation. Do not float.
4 BP passive Reference-noise bypass pin (fixed-voltage version). Connect a low-leakage 0.01 µF ceramic capacitor from BP to GND, placed very close to the pin, to reduce output noise and improve PSRR. Leave open if bypass is not desired.
5 OUT power_out Regulated 3.3 V output, up to 500 mA (current limit typ. 800 mA with foldback). Requires a 1 µF ceramic output capacitor to GND for stability. Load regulation ~20 mV (IOUT 0.1 mA to 300 mA).

Two STEP files. Same geometry, different body top:

File Size Use it when
rs3236-3-3yf5.step 85 KB You want the bare part, or you mark your own boards.
rs3236-3-3yf5-etched.step 2.7 MB You want the part with RS3236-3.3YF5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 633 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.
