ME2107A50M5G from MICRONE, 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 | EN | input | Enable input with true shutdown when pulled low; at VIN=2 V the high threshold is 0.8×VIN (1.0-1.5 V for the VOUT=5.0 V version) and the low threshold is 0.2×VIN (0.4 V for the 5.0 V version), with absolute maximum -0.3 to 6 V. |
| 2 | GND | power_in | Ground pin, which the datasheet says must be well grounded because switching current otherwise shifts the internal zero-potential reference and destabilises operation. |
| 3 | VBAT | power_in | Input supply pin with absolute maximum rating -0.3 to 6 V, a specified maximum operating input of 0.9 to 5.5 V, and a 0.9 V typical start-up voltage at 1 mA load. |
| 4 | VOUT | power_out | Boost regulator output with absolute maximum rating -0.3 to 6 V, a 1.8 V to 5.0 V output in 0.1 V steps at ±2% accuracy, and a 0.1 µF ceramic capacitor recommended between VOUT and GND. |
| 5 | LX | output | Switching node connected to the inductor and internal power switch, with absolute maximum voltage -0.3 to 6 V and maximum LX current of 1000 mA. |
