LT3028IDHC#TRPBF is a low-dropout linear regulator (LDO) integrated circuit (IC) manufactured by Linear Technology Corporation (LTC). It is part of the LTC\'s family of low-noise, low-dropout voltage regulators. It is designed for applications that need a low-noise, high-accuracy voltage regulator over a wide operating temperature range. The IC is offered in a 8-pin plastic small outline package and is designed for power supply requirements in multiple power domains.

Application Field

The LT3028IDHC#TRPBF is designed for use in a variety of general-purpose applications, such as in parallel power buses, automotive noise sensitive applications, telecommunications, and portable/handheld device power. It is well-suited for use in any system requiring an accurate and low-noise voltage regulation. It is ideal for applications which need high stability, noise suppression, and dynamic response. The device is ideal for use in systems where the power supply voltage is constantly varying due to current demands, thermal effects, and process variations.

Working Principle

The LT3028IDHC#TRPBF is a single-channel low-dropout linear regulator (LDO). It has a low 10-uA current requirement, an improved low-noise performance, and a wide operating temperature range of -40 to +125 °C. The device uses an internal PNP series pass element and an output voltage reference. The PNP series pass element regulates the voltage supplied at the input. This element regulates the output voltage by changing the series impedance of the device in response to changes in the input voltage, effectively controlling the current through the device. The output voltage reference defines the output voltage. It controls the series pass element and ultimately, the output voltage.

The superior performance of the LTC3028IDHC#TRPBF is achieved by its low noise and load regulation of the device. The device has a low quiescent current of 10 uA and can deliver a low output voltage ripple of 1 mV. The LTC3028IDHC#TRPBF is also able to deliver a high input voltage transient rejection ratio of 750 mVpp, which makes it suitable for use in automotive applications. The LT3028IDHC#TRPBF also offers a high load regulation of 0.5% to 0.8%, making it suitable for use in power-sensitive applications.

Conclusion

In conclusion, the LT3028IDHC#TRPBF is an Integrated Circuit that was designed for use in a variety of general-purpose applications. It offers superior performance with its low quiescent current, low output voltage ripple, high input voltage transient rejection, and high load regulation. The LT3028IDHC#TRPBF is well-suited for use in systems where the power supply voltage is constantly changing because of current demands, thermal effects, or process variations.
