The TL1431CZ is a voltage reference integrated circuit (IC) intended for precision voltage regulation and reference applications. The TL1431CZ is specifically designed to provide a low temperature coefficient and low noise operation when combined with other precision components on an application board. The TL1431CZ is part of a growing portfolio of precision voltage reference products from Texas Instruments (TI) and is based on their proven TranslinearTM voltage regulation technology. The TL1431CZ is primarily targeted for use in low noise, low temperature drift circuits.
The TL1431CZ consists of two sections: the voltage reference section and the voltage buffer section. The voltage reference section provides a stable output voltage over temperature, with a low temperature coefficient. The voltage buffer section provides the additional gain needed to achieve the desired output voltage. The output voltage is set by an external voltage divider network and is adjustable from 0.3V to 5.5V.
The TL1431CZ can provide a wide range of output voltages, with a variety of output currents, by using an external capacitor. The output current is set by an internal current source. The current source can be configured in either constant current or constant voltage modes. The output voltage is regulated to ensure that it remains constant over temperature, with a low temperature coefficient. The output voltage is also temperature compensated to maintain its stability over temperature.
The TL1431CZ has been designed with low noise operation and low output noise (below 43 dB). TheTL1431CZ also has a very low drop-out voltage and can handle load transients with a minimum of disruption. TheTL1431CZ also uses a low power, low quiescent current design which results in low power dissipation and improved efficiency. This makes the TL1431CZ an ideal choice for use as a voltage reference in power management and other power converter applications.
The TL1431CZ is an excellent choice for applications such as medical instrumentation, power supplies, and voltage reference designs, where low output noise, low temperature coefficient, and low output voltage regulation are key requirements. The TL1431CZ has been designed to allow for flexibility in the output voltage and current, making it suitable for a wide range of applications. In addition, the TL1431CZ is low power and easy to use, making it an ideal choice for most precision voltage reference designs.
