MAX6143BASA50+T is a Voltage Reference product developed by Maxim Integrated focused on Precision Voltage Regulation. It liquid crystal display bias and Automotive DC to DC power supply applications. The device is designed to provide a positive or negative output voltage of +3.3 V to -3.3 V over the temperature range of -40°C to +85°C.

The MAX6143BASA50+T is a 3-terminal programmable voltage reference that is configurable on-the-fly via an external resistor. The internal reference voltage (VREF) can be selected in 0.01V increments by using the external resistor. It features an ultra-low typical 7mV dropout voltage and low 1.5uA maximum supply current. It provides excellent reference accuracy of ±5mV over temperature.

The device consists of a molecular, temperature-compensated precision voltage reference, an output voltage level translator, and a low-dropout voltage regulator, allowing the reference output voltage to range from 1V to 4V. The reference output voltage is trimmed to a guaranteed level of accuracy and is maintained constant over a wide range of temperature and load issues. It integrates a 0.1% (maximum) noisy oscillation rejection circuitry that filters out noisy loads in the system.

Features of this IC also include a low-power shutdown mode (VSTBY) which reduces IC power dissipation to less than 1uA when enabled. In addition, this device can be operated over a wide temperature range of -40°C to +105°C. The output voltage accuracy is guaranteed to be within 0.5% over the temperature range.

The MAX6143BASA50+T can be used in many applications that require an ultra-stable voltage reference such as AC/DC Power Supply, Automotive DC to DC supply, portable equipment, precision analog measurement systems and general voltage regulation. It is also used to bias LCD displays, PLLs and comparators in many portable electronic devices. Furthermore, it can be used in systems that require a reliable voltage reference for current monitoring.

In short, the MAX6143BASA50+T is an ideal choice for fast, low-noise precision voltage regulation. It offers a high degree of accuracy and stability for a wide range of applications, making it a reliable and cost-effective solution for many different types of designs.
