The MAX6138AEXR12+T is a precision, low-dropout microprocessor voltage reference from Maxim Integrated. This device offers a fixed reverse breakdown voltage of 1.2V with an impressive accuracy of ±0.2% at room temperature. It is designed to maintain stability and accuracy over a wide range of operating conditions, making it an ideal choice for high-performance applications that require a reliable reference voltage.

The MAX6138AEXR12+T features a low temperature coefficient, typically 35ppm/°C, which ensures minimal deviation from its specified voltage over the entire -40°C to +125°C temperature range. This stability is crucial for applications requiring consistent performance regardless of temperature fluctuations.

One of the standout features of this voltage reference is its low dropout voltage, which enables it to maintain accurate output even with minimal difference between the input and output voltages. This makes it particularly useful for battery-powered devices where preserving power is essential. The device also boasts a low supply current of 160µA (max), further contributing to energy efficiency.

The MAX6138AEXR12+T is available in a small, 3-pin SC70 package, making it suitable for space-constrained applications. Its small footprint is complemented by its robustness, with the ability to source or sink 500µA of load current, providing designers with a versatile and compact voltage reference solution.

This voltage reference also includes a force-sense connection that enhances the accuracy of the output voltage by eliminating errors due to PCB trace resistance. This feature is especially beneficial in precision applications.
