MCP1541T-I

Microchip · Voltage Reference · SOT-23

MCP1541T-I from Microchip, in a SOT-23. 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 VIN power_in Input (operating) voltage pin. Accepts 4.3V to 5.5V for the MCP1541. Input current is typically 86 µA (100 µA max at +25°C) with no load. Recommended optional 0.1 µF ceramic input bypass capacitor.
2 VOUT output Precision reference output pin, nominal 4.096V (4.055V to 4.137V). Drives up to ±2 mA. Requires a load capacitor CL between 1 µF and 10 µF to VSS for stability. Dropout voltage is typically 137 mV at IOUT = 2 mA.
3 VSS power_in Ground reference pin for the device. Return for both input supply current and output load current.
