PMIC - Voltage Reference

TL431IDBZRG4 is a three-terminal adjustable Linear Voltage Reference device that is designed for operation from a single supply voltage. This voltage reference device is manufactured by Infineon Technologies, and it provides accurate, temperature-stable and programmable voltage reference. It is available in a small package of 8-lead SOIC.

The TL431IDBZRG4 is a programmable shunt regulator with an internaltemperature compensated bandgap reference and an error amplifier todeliver a stable output over a wide range of environmental andload conditions. This voltage reference device is designed to operateover a wide range of temperature conditions and draw very little quiescentcurrent.

The main function of TL431IDBZRG4 is to provide a regulated voltageto a load. It does this by monitoring the output voltage, comparing itto the internal reference voltage and then adjusting the output voltageaccordingly. TL431IDBZRG4 can provide an adjustable output voltage from2.5V to 36V with a ±2.2% accuracy. It can also provide an adjustablecurrent from 1mA to 20mA with a ±1.75% accuracy. The adjustableoutput voltage and current can be easily set by two external resistors.

The TL431IDBZRG4 can operate over a wide range of temperatureconditions, from -40°C to 125°C. Its high accuracy and low temperaturecoefficient make it well suited for applications that require precisevoltage reference, such as in regulated power supplies, batterychargers, portable devices and precision A/D converters. It also hasvery low quiescent current of only 2μA, which is beneficial inapplications where power consumption is critical.

The advantages of TL431IDBZRG4 include its small size, low powerconsumption, wide range of temperature conditions and low outputresistance. This makes it well suited for use in space constrainedenvironments and a variety of other applications. The TL431IDBZRG4can be used as a general purpose voltage reference, a precision voltageregulator, or a current regulator.

In summary, TL431IDBZRG4 is an adjustable Linear Voltage Referencedevice manufactured by Infineon Technologies. The device offers anaccurate, temperature-stable and programmable voltage reference. Itcan provide an adjustable output voltage from 2.5V to 36V with a±2.2% accuracy, and adjustable current from 1mA to 20mA witha ±1.75% accuracy. The device has a wide range of temperature range(-40°C to 125°C) and low quiescent current of only 2μA. This makesit well suited for applications such as regulated power supplies,battery chargers, portable devices and precision A/D converters.
