SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
SGM2028-ADJYN5G from SGMICRO, 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 | Regulator input; supply voltage can range from 2.5V to 5.5V, and the input should be bypassed with a 1μF capacitor to GND. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Shutdown input; a logic low reduces the supply current to 10nA, and it should be connected to IN for normal operation. |
| 4 | FB | input | Feedback pin for the adjustable voltage version, used to set the output voltage of the device. |
| 5 | OUT | power_out | Regulator output. |
