RYCHIP · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
RY6212-28M5R 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; the recommended input range is 2V to 5.5V. |
| 2 | GND | power_in | Ground pin; the EPAD is not present on this package, so GND is the only ground connection. |
| 3 | EN | input | Active-high enable control: driving EN above 1V turns on the regulator and driving EN below 0.5V puts it into shutdown mode. |
| 4 | NC | unconnected | Not connected. |
| 5 | OUT | power_out | Output voltage pin for the regulator; for the RY6212-28M5R this is the 2.8V fixed output, with output current up to 350mA. |
