TLE42754GATMA1 Integrated Circuits (ICs)

PMIC - Voltage Regulators - Linear

TLE42754GATMA1 is an advanced linear voltage regulator. Linear voltage regulators are often used in applications that require a very low-noise power supply, as it uses an active component to provide an output voltage that is regulated as input voltage and load current changes. Its output voltage is adjustable, and an external reference voltage is required to do so. It also provides a good current limiting feature, and its internal circuitry keeps the output voltage stable under varying line and load conditions.

TLE42754GATMA1 is a high-efficiency, low-dropout linear regulator with a low quiescent current of only 2 mA. It also features thermal shutdown and current limit protection, which makes it suitable for use in applications where safety and reliability are of paramount importance. It is also suited for automotive and other harsh environmental applications because of its excellent surge immunity and ESD protection.

The application field of TLE42754GATMA1 Voltage Regulator mainly include the automotive, medical, industrial, and consumer markets, where current consumption and device footprint need to be minimised and reliability is high. It can also be used in instrumentation applications, as it is designed to handle high transient currents.

The working principle of the TLE42754GATMA1 Voltage Regulator is fairly simple. It employs a pass transistor with a source to source resistance (RSS) to regulate the output voltage. The output voltage is determined by the ratio of the RSS and the reference voltage, the reference voltage being adjustable by a resistor network connected to the voltage adjust pin. When the output voltage of the regulating device is higher than the voltage set by the reference voltage, the pass transistor will turn OFF and the power will be shut off. Similarly, when the output voltage is lower than the voltage set by the reference voltage, the pass transistor will turn ON, allowing power to be delivered to the load.

TLE42754GATMA1 Voltage Regulator is a high-performance device that provides low-noise power supply and current limiting features. Its high efficiency, low-dropout, and low quiescent current make it suitable for use in automotive, medical, and industrial applications. Its excellent surge immunity and ESD protection make it suitable for harsh environmental applications.
