ME2108A33PG 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; the datasheet requires a solid ground connection because switching current otherwise shifts the IC's internal zero level and can make operation unstable. |
| 2 | Vout | power_out | Output voltage monitor and IC internal power supply; the output is programmable from 2.0V to 7.0V in 0.1V steps, and the external capacitor should be connected with minimum trace length. |
| 3 | Lx | output | Switch pin that drives the inductor through the internal Lx transistor; the absolute maximum Lx pin voltage is 6.5V and the Lx pin current is rated at 600mA. |
