TLE4291EXUMA1

PMIC - Voltage Regulators - Linear

TLE4291EXUMA1 is a linear voltage regulator with integrated OVP, which is designed in LM2941 standard. It provides a bright white LED driver with a wide input voltage range from 7V to 28V for various applications.

By applying the OVP, this linear voltage regulator is suitable for very low voltage applications. It limits the output voltage through the resistor. When the input voltage is higher than the rated voltage, the current reduces to protect the circuit. It provides a steady output voltage with low noise and a wide-temperature range.

Application Field

TLE4291EXUMA1 voltage regulator is a perfect solution for a variety of applications, such as industrial lighting and audio, consumer electronics and home appliances, automotive audio and video, consumer hand-held devices and so on. It has a wide input voltage range of 7V to 28V, can support a wide temperature range from -40℃ to 125℃ and low operating current of 4mA.

Working Principle

The working principle of TLE4291EXUMA1 linear voltage regulator is based on the Zener diode and a low offset voltage operational amplifier. When the input voltage is higher than the rated voltage, this voltage regulator will reduce the current to protect the circuit. It is also able to protect the circuit from voltage spikes by the OVP feature.

The TLE4291EXUMA122 voltage regulator has an integrated 2.5V voltage reference and a low-noise current feed-back to make sure the output is stable and reliable. Also, it provides a good output ripple rejection performance and line/load transient response.

Conclusion

TLE4291EXUMA1 is a perfect example of a linear voltage regulator which integrates OVP feature offering bright white LED lighting. It is suitable for a variety of low voltage applications, provides steady output voltage with low noise and wide-temperature range.
