TCR3DF28,LM(CT

TCR3DF28 LM (CT application field and working principle):

TCR3DF28 LM is a linear voltage regulator from the PMIC (power management integrated circuit) family. It is also known as an adjustable voltage regulator or low drop-out regulator (LDO). The device is designed to provide a regulated output voltage from a higher input voltage. The regulator has a wide input voltage range and can provide up to a few hundred mA of current. The TCR3DF28LM is suitable for a wide range of applications, from automotive and industrial to consumer electronics.

The TCR3DF28LM operates with an adjustable output voltage and can be set by an external resistor network. Internal compensation provides stability and excellent line/load response. The device is available with an input voltage range of 8 V to 28 V, and an output voltage range of 0.8 V to 28 V. The typical drop out voltage is 0.6 V with a maximum input-output differential of 28 V unregulated. This makes it suitable for a wide range of applications, such as automotive and industrial, where a low drop-out voltage is critical.

The device features a high-efficiency switching modulator, which minimizes power consumption and provides a fast transient response. The TCR3DF28LM achieves a maximum efficiency of 97% across the entire operating range, thus providing extended battery life. The device is designed to be extremely compact and is available in small SOT-223 packages, making it ideal for applications with limited space requirements, such as portable devices.

The TCR3DF28LM features over-voltage, over-temperature, reverse voltage and short-circuit protection. The device is protected against thermal runaway and transient overstress. The over-voltage protection limits the output voltage to a preset level in order to protect downstream components. The reverse voltage protection prevents reverse current flow and consequent power losses. The device also provides a maximum peak current limit of 1.5 A.

In summary, the TCR3DF28LM is a highly efficient and user-friendly linear voltage regulator from the PMIC family. It is suitable for a wide range of applications, from automotive and industrial to consumer electronics. The device features an adjustable output voltage, high-efficiency switching modulator, and protection against voltage, temperature, and current overstress. The device is available in compact SOT-223 packages, making it an ideal choice for a variety of applications.
