Maxim Integrated MAX875BCPA Low-Power, Low-Dropout Voltage Reference

The MAX875BCPA from Maxim Integrated is a precision, low-power, low-dropout voltage reference designed for a wide array of applications requiring a stable and accurate reference voltage. This device is particularly well-suited for battery-powered equipment, data converters, and power supplies, thanks to its low quiescent current and stable operation over a broad range of temperatures and supply voltages.

The MAX875BCPA offers a fixed output voltage of 5V, with an impressive temperature coefficient of just 20ppm/°C, ensuring minimal drift across the operating temperature range of -40°C to +85°C. This makes it an ideal choice for high-precision analog circuits where temperature-induced voltage variations cannot be tolerated.

One of the key features of the MAX875BCPA is its low dropout voltage, which allows the reference to maintain accurate output even when the supply voltage is very close to the output voltage. This characteristic is particularly important for battery-operated devices, where maximizing the usage of the available battery voltage is crucial.

The MAX875BCPA also boasts a low supply current of typically 180µA, which is beneficial for power-sensitive applications. Its no-load supply current is almost independent of the supply voltage, providing additional power savings. The device is offered in an 8-pin DIP package, which is widely used and easy to integrate into various circuit designs.

In terms of protection, the MAX875BCPA features short-circuit and reverse battery protection, ensuring the device's reliability and longevity in the face of potential mishaps. Its high precision and robust protection mechanisms make it a dependable choice for critical applications where voltage reference stability is paramount.

Overall, the Maxim Integrated MAX875BCPA is a versatile and reliable voltage reference that combines high precision with low power consumption, making it an excellent choice for designers looking to enhance the performance of their analog circuits.
