RT9080-28GJ5-MS from MSKSEMI, 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 | Power input for the LDO, specified for 1.2V to 6V operation, with an input capacitor of 1µF or larger placed close to the VIN and GND pins. |
| 2 | GND | power_in | Ground pin; the input and output capacitor ground connections must return to this pin using short, wide traces. |
| 3 | EN | input | Enable control: EN is specified with a rising threshold of 1.7V (VIH) and a falling threshold of 0.6V (VIL), and pulling it low enters shutdown, where quiescent current drops to about 10nA typical (enable-pin versions only). |
| 4 | NC | unconnected | No internal connection; the pin is floating and is not used on this part. |
| 5 | VOUT | power_out | Regulated output for the 2.8V fixed-output variant, rated for up to 600mA load current and requiring a ceramic or tantalum output capacitor of 1µF to 22µF with ESR above 1mΩ placed close to VOUT and GND. |
