TLE4253GSXUMA1 is an adjustable linear voltage regulator manufactured by Infineon Technologies AG. It is a 3-terminal monolithic integrated circuit suitable for use in applications such as voltage converters and automatic voltage stabilizers. As a voltage regulator, it stabilizes a targeted output voltage by automatically adjusting the current flow through its output. The TLE4253GSXUMA1 can handle output current up to 1.5A, making it suitable for a wide range of applications where low power dissipation and accurate adjustment and monitoring of the output voltage is needed.

Application Field of TLE4253GSXUMA1

The TLE4253GSXUMA1 is suitable for a wide range of linear voltage regulation applications such as voltage converters, automatic voltage stabilizers, power converter/inverters, and power supplies. The lightweight, small-sized design of the TLE4253GSXUMA1 makes it suitable for portable and handheld devices. It can also be used in industrial, automotive and telecommunications applications where reliable voltage regulation is a must.

Working Principle of TLE4253GSXUMA1

The TLE4253GSXUMA1 functions by using an internal voltage regulator to control the output voltage. It has an adjustable reference voltage, which can be set via an external resistive divider, that sets the reference voltage. The controlled current running through the output will then be adjusted accordingly to meet the reference voltage level, thus stabilizing it. In case of load transients, the TLE4253GSXUMA1 can handle the maximum output current provided by its 1.5A protection resistor, allowing quick and accurate voltage stabilization.

The TLE4253GSXUMA1 also includes a sleep mode feature that allows the circuit to be shut down during periods when the output voltage is not needed. This protects the circuit from voltage overshoots and shorts. The sleep mode feature also improves the overall efficiency of the circuit and reduces power dissipation. Furthermore, the TLE4253GSXUMA1 is equipped with over-voltage and short-circuit protection for added safety and security.

The TLE4253GSXUMA1 linear voltage regulator also has an adjustable reset function. The reset function allows the circuit to be reset if the output voltage exceeds a certain predetermined value. The reset time is adjustable and can be set to values from 500 ns to 20 µs.

The TLE4253GSXUMA1 is a versatile and reliable voltage regulator suitable for a wide range of applications. With its adjustable reference voltage, adjustable output current limitation, sleep mode, and reset function, the circuit offers an economical and convenient solution for voltage regulation.
