ME2109FM5G

MICRONE · DC-DC Converters · SOT-23-5

ME2109FM5G from MICRONE, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FB input Feedback voltage input. Compares the divided output voltage against the internal 1.25 V reference (VFB typ 1.25 V, min 1.225 V / max 1.275 V) to regulate VOUT. Set VOUT with R1/R2 divider, keeping R1+R2 < 50 kΩ.
2 VDD power_in IC power supply pin. Recommended operating range 1.8 V ≤ VDD < 6 V (absolute max 6.5 V). Start-up guaranteed from 0.9 V at IOUT = 1 mA.
3 CE input Chip enable / shutdown pin. VCE ≥ 0.75 V enables oscillation; VCE ≤ 0.3 V (VOUT ≥ 1.5 V) or ≤ 0.2 V (VOUT < 1.5 V) forces shutdown (ISSS typ 0.01 µA). Absolute max: -0.3 V to VIN+0.3 V.
4 GND power_in Ground reference pin for the IC.
5 EXT output External N-channel power MOSFET gate drive output. Sourcing IEXTH typ -25 mA (VEXT = VOUT-0.4 V), sinking IEXTL typ 40 mA (VEXT = 0.4 V). Absolute max current ±1000 mA. Voltage limited to VDD+0.3 V.
