MCP1525-I

Microchip Tech · Voltage Reference · TO-92-3

MCP1525-I from Microchip Tech, in a TO-92-3. 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 VSS power_in Ground (or negative power supply) pin, normally connected directly to ground; it can sit at another voltage only if all voltages shift with it and proper bypassing is observed.
2 VOUT output Accurate reference voltage output that can source and sink small currents with low output impedance, and needs a load capacitor between 1 µF and 10 µF located within 5 mm of the pin.
3 VIN power_in Positive power supply (operating) input, which must be at least 0.2V higher than the output voltage for normal operation; the datasheet gives an input range of 2.7V to 5.5V for the MCP1525.
