ME3103AM5G

MICRONE · DC-DC Converters · SOT-23-5

ME3103AM5G 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 EN input Enable input. Drive high (>=1.5V, VEH) to enable the converter; drive low (<=0.3V, VEL) to shut down the device (Isd typ 0.1uA). EN must not exceed VIN.
2 GND power_in Ground reference for the device and the low-side synchronous NMOS rectifier return.
3 SW output Switching node. Connect the external inductor (1uH-4.7uH typ) between SW and the output. Absolute maximum -0.3V to VIN+0.3V; typical SW leakage +/-1uA.
4 VIN power_in Input supply pin, 2.5V to 5.5V operating range (6.0V absolute maximum). Bypass with a low-ESR ceramic capacitor (22uF X5R/X7R typical) close to the pin.
5 FB input Feedback input to the internal error amplifier. Regulates to VFB=0.6V (typ, 0.588V-0.612V). Output voltage is set by an external R1/R2 divider: VO = 0.6 x (1 + R1/R2). Absolute maximum -0.3V to VIN.
