RY6212-33M5R from RYCHIP, 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 | VIN | power_in | Input voltage pin for the regulator, with an operating input range of 2V to 5.5V and an absolute maximum VIN of 6V. |
| 2 | GND | power_in | Ground pin of the regulator. |
| 3 | EN | input | Active-high enable control: driving EN above 1V turns the regulator on, and driving EN below 0.5V puts it into shutdown mode. |
| 4 | NC | unconnected | Not connected. |
| 5 | OUT | power_out | Output voltage pin of the regulator; for the RY6212-33M5R the nominal output is 3.3V with ±2% output voltage tolerance. |
