ME2107A50M5G

MICRONE · DC-DC Converters · SOT-23-5

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.
