Working Principle:

The LT1965IQ-2.5#TRPBF is a linear voltage regulator, featuring a low dropout regulator functionality. It works by constantly comparing the actual output voltage to the desired voltage. When the actual voltage is lower than the desired voltage, the regulator supplies the required amount of current to the output, thus raising the output voltage. Conversely, when the actual voltage is higher than the desired voltage, the regulator decreases the current and thus strives for the desired output voltage. This ensures that the output voltage remains as close to the desired voltage as possible.

The LT1965IQ-2.5#TRPBF also offers a current limiting feature, which is especially useful in applications with high current requirements. The device is able to limit the output current to the specified level, avoiding any damages to the system as a result of excessive current.

The other features offered by the LT1965IQ-2.5#TRPBF includes under voltage lockout (UVLO) and over temperature shutdown (OTS) for enhanced reliability. It also includes an open-drain error flag, which can be used to indicate an overtemperature condition, an overcurrent condition, or an undervoltage lockout condition, thus making it suitable for use in safety and critical applications.

In conclusion, the LT1965IQ-2.5#TRPBF is a linear voltage regulator from Linear Technology, offering a wide input voltage range, adjustable output voltage and current, as well as additional features such as UVLO, OTS and a open-drain error flag for enhanced reliability and safety. It is suitable for a wide range of applications such as cellular phones, PDAs and other portable electronics.
