The ZR431C01L Voltage Reference is a precision fixed-output voltage reference, offering excellent stability and accuracy. It is a 3.3V, 2mA reference with a temperature coefficient of 0.4ppm/C. It is suitable for both commercial and consumer application, such as D/A converters, power supplies, transducer readouts and various peripherals requiring a stable, accurate supply.

The ZR431C01L is available in a 32-pin quad flat no-lead (QFN) package and features on-board adjustments for user trim and over-temperature protection. The ZR431C01L is designed to minimize power consumption and supply noise while maintaining high accuracy and zero drift performance. It also offers power-on reset circuitry and disable functions.

The ZR431C01L operates by converting an input voltage to a fixed-output voltage. The output voltage is determined by an internal resistor network. This resistor network is precision-trimmed to match the reference output voltage, thereby providing excellent accuracy and stability. The resistor network is also decoupled from the reference output, so that any variation in the input voltage is not transferred to the output.

The ZR431C01L is designed to provide a stable, precise supply voltage under varying ambient temperature and input voltage conditions. The device has temperature coefficient of 0.4ppm/C, which ensures high accuracy even at extreme temperatures. The device also has a power supply rejection ratio (PSRR) of 0.1mV/Vrms, which ensures high accuracy across the entire operating temperature range.
