MAX873 datasheet



This is a low-dropout (LDO) linear voltage regulator manufactured by Maxim Integrated.

The MAX873 / MAX875 / MAX876 precision 2.5V, 5V, and 10V references offer excellent accuracy and very low power consumption. Extremely low temperature drift combined with excellent line and load regulation permit stable operation over a wide range of electrical and environmental conditions.

Operation for the MAX873 is guaranteed with a +4.5V supply, making the part ideal in systems running from a +5V ±10% supply. Low 10Hz to 1kHz noise—typically 3.8µVRMS, 9µVRMS, and 18µVRMS, respectively, for the MAX873, MAX875, MAX876—make the parts suitable for 12-bit data-acquisition systems.

The MAX873 is designed for a wide range of applications, including portable devices, handheld devices, and battery-powered systems, where a low-power, high-precision voltage regulation is required. It provides fast transient response, low output noise, and excellent line and load regulation, making it a reliable and versatile voltage regulator.
