TLVH431BCDCKR is a voltage reference IC, which belongs to the power management integrated circuit (PMIC) family. A voltage reference is an electronic circuit, designed to provide a constant, precise reference voltage regardless of power supply line disturbances, load disturbances, temperature changes and other external disturbances. It operates as the voltage reference point in electronic circuit designs.For TLVH431BCDCKR Application, it is mainly used in circuits where a precise reference voltage is needed. For example, analog-to-digital converters, sample-and-hold circuits, precision amplifiers, and digital-to-analog converters. TLVH431BCDCKR is a low cost and low power voltage reference IC with low temperature drift that combines both operational amplifiers and references in a single package. The TLVH431BCDCKR features the highest accuracy of 0.05% and the lowest max temperature coefficient of 15 ppm /°C of any 1.2 V voltage reference. This same low temperature coefficient is seen with temperature range of -40°C and +85°C. It offers very low quiescent current of 900 nA and input/output protection to 18 V. The TLVH431BCDCKR voltage reference is mechanically compatible with the industry-standard TO-92, SO-8 and SC70 packages.TLVH431BCDCKR is a voltage reference IC which works by relying on the internal voltage reference generated by the on-chip bandgaps. The reference voltage generated by the internal bandgap is actually dependent on the temperature of the device, and will shift as the system temperature changes. To compensate for the temperature based shift of the reference voltage, precision resistors are used in combination with a bridge circuit. This bridge is used to adjust the voltage output, allowing it to remain the same relative to the reference voltage, regardless of temperature changes.It requires only one capacitor at the input to provide a stable voltage reference and a second capacitor at the output, to provide a ripple free output. This provides a fixed and stable voltage output that is free of any external noise and temperature fluctuations.To sum up, TLVH431BCDCKR is designed to provide a constant, precise reference voltage regardless of power supply line disturbances, load disturbances, temperature changes and other external disturbances. It is mainly used in circuits where a precise reference voltage is needed. It is a low cost and low power voltage reference IC with low temperature drift, with a very low quiescent current of 900 nA and input/output protection of 18 V.
