The LD29150DT25R is a low-dropout (LDO) voltage regulator specifically designed for use in computer peripheral, communications, consumer electronics and automotive applications. It features an adjustable output voltage, a low quiescent current, an Active-High Shutdown, an Enable function, an Output Disconnect function and an operational temperature range of -40°C to +125°C. The LD29150DT25R is also compliant with the I2C bus standard.

It is important to understand the application field and working principle of the LD29150DT25R if you are considering using it as a voltage regulator in your industrial or consumer products. This regulator supports a variety of input voltages from 3.0 to 17.0V and is able to provide regulated output voltages ranging from 0.8 to 15V with load current ratings of up to 1.5A. It has a guaranteed accuracy of ±1%.

The LD29150DT25R voltage regulator uses an internal low-bias current, high-gain amplifier to provide regulation of the output voltage. This amplifier compares the feedback signal to a reference voltage generated internally and adjusts the output voltage accordingly. This regulator also includes a current limit circuit which provides protection against current overloads, ensuring that the output voltage remains at the required level.

The LD29150DT25R also includes an active-high shutdown and an enable function, both of which can be controlled via I2C bus. The shutdown mode is enabled when the SDA and SCL pins are pulled low and the enable mode is enabled when the SDA and SCL pins are pulled high. The enable pin will cause the output voltage to fall to ground when disabled.

The LD29150DT25R also includes an output disconnect function, which is enabled when the SDA and SCL pins are pulled low and the enable pin is high. This will result in the output voltage being disconnected from the input voltage, protecting the regulator against transients and overloads.

In summary, the LD29150DT25R is a low-dropout voltage regulator specifically designed for use in applications such as computers, communications, consumer electronics and automotive applications. It is able to support a wide range of input and output voltages, has an active-high shutdown, enable and output disconnect functions, and is compliant with the I2C bus standard. It offers improved accuracy and excellent performance, making it an ideal choice for those who require a highly accurate, reliable and affordable voltage regulator.
