RY6212-ADJM5R 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 | IN | power_in | Input voltage pin for the regulator, with a recommended VIN range of 2 V to 6.5 V and a 1 µF to 10 µF input capacitor between VIN and GND. |
| 2 | GND | power_in | Ground pin; keep the wiring resistance between VIN and GND low, since high impedance there can make operation unstable. |
| 3 | EN | input | Enable control: driving EN above 0.9 V turns the regulator on and below 0.4 V puts it into shutdown, and the standard type is High Active/No Pull-Down so EN must not be left open. |
| 4 | FB | input | Feedback pin for the adjustable output option, where VOUT = 0.8 × (1 + R1/R2) and R2 must be at least 100 kΩ. |
| 5 | OUT | power_out | Output voltage pin for the regulator, with a recommended output current of 0 mA to 300 mA and an output capacitor of 1 µF to 10 µF placed as close as possible to OUT and GND. |
