The TL431CDBZR,215 series is an IC designed for use as a low-temperature and high-temperature low-voltage voltage reference. It is a 3-terminal adjustable precision shunt regulator, providing a highly regulated output of 215mV at rated temperature and load. TL431CDBZR,215 series is part of the PMIC (power management integrated circuit) family, and is useful in providing a highly accurate and stable voltage reference for a variety of applications. It uses a high-precision band gap reference and a high accuracy-temperature compensation circuit, resulting in a steady, low-power and low-output noise output. It is also suitable for a wide range of operating temperatures, from -40°C to 85°C.The TL431CDBZR,215 series is widely used in various electronic systems such as voltage monitoring, data acquisition systems, high-power and high-current regulation, voltage gain control systems, power sources, and more.In terms of installation, the TL431CDBZR,215 comes in a small, two-pin SOT-23 package and is easy to install in tight spaces. It is also compatible with both leaded and surface mount installations.The TL431CDBZR,215 series works based on the concept of a constant-current shunt regulator. Its three-terminal configuration is designed to regulate the voltage depending on the current flowing through the reference and feedback terminals. The regulating output is determined by the setting of the external resistor, with the nominal output of 215mV set by a single 1K ohm resistor. The voltage can be adjusted by varying the ratio between the top-to-bottom resistor value. Generally, for a given output voltage, the ratio between the two resistors is set such that the upper resistor is set to a few times the lower resistor, usually from 5 to 15 times.The TL431CDBZR,215 series also features over-voltage session protection and temperature compensation to make it more resistant to fluctuating voltages and environmental changes. This ensures that the device maintains a stable output even when the input voltage varies or the temperature changes. It also features an automatic shutdown circuit which turns the output off when the voltage exceeds the threshold.Overall, the TL431CDBZR,215 series is an excellent choice for applications that require low-power, low-voltage, and highly accurate voltage references. With its highly stable output, wide temperature range, and easy installation, it is a useful tool in various applications.
