ME2108A27PG from MICRONE, in a SOT-89-3. 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 | Vss | power_in | Ground pin; make Vss sufficiently grounded on the PCB so the IC's internal zero level does not vary with switching current. |
| 2 | Vout | power_in | Output voltage monitor and IC internal power supply; output set in 0.1V steps from 2.0V to 7.0V with ±2.5% accuracy. |
| 3 | Lx | output | Switch pin (internal Lx transistor drain) connecting to the inductor; absolute maximum 6.5V and 600mA. |
