The TL432IDBVRG4 is a three-terminal adjustable shunt regulator with a nominal output voltage of 2.495V and a 2% accuracy. It is designed for use as a precision voltage reference in a wide range of applications, such as battery-powered systems, avionics, and automotive systems. The device is available in an SOIC package and is available over a wide operating temperature range (-40 to 125°C).

The TL432IDBVRG4 belongs to the family of Precision Voltage References (PMIC - Voltage Reference), which are used to provide a precise voltage reference point in voltage-controlled systems. A voltage reference is a precise voltage source, typically with low output impedance, that is used to maintain precise output voltages (e.g., in power supplies, logic circuits, analog systems, etc.). The PMIC voltage references are designed to provide precise, stable output voltages over a wide operating temperature range.

The working principle of TL432IDBVRG4 is based on an error amplifier, which is designed to maintain an output voltage that is derived from an external reference voltage (VREF) and a resistor divider network. The error amplifier compares the output voltage to a reference voltage and adjusts its output to bring the output voltage (VOUT) back to the desired value. The error amplifier output is used to control a series N-channel power MOSFET, which serves as the series pass device for the shunt regulator.

The TL432IDBVRG4 is designed with high accuracy, low temperature drift, and low noise output. It also supports a wide operating temperature range and is suitable for use in battery-powered systems. The device includes a shut-down comparator, which can be used to reduce the output voltage when the input voltage falls below an adjustable threshold. This helps to conserve power in battery-powered applications by reducing the output voltage to an acceptable level.

In short, the TL432IDBVRG4 is a three-terminal adjustable shunt regulator with a nominal output voltage of 2.495V and a 2% accuracy, designed for use as a precision voltage reference in a wide range of applications. It features high accuracy, low temperature drift, low noise output, and supports a wide operating temperature range. It is a member of the Precision Voltage References (PMIC - Voltage Reference) family and is designed to provide precise, stable output voltages over a wide operating temperature range.
