PMIC - Voltage Regulators - Linear

The LT3081HT7#PBF is a linear voltage regulator that belongs to Linear Technology’s family of high-precision, low-dropout, ultra-low-noise, high-load-capable, low-bias current linear regulators. It is specifically designed to ensure the best performance with high-accuracy requirements and tight load/line regulation.

This device provides a cost-effective alternative to switching regulator solutions that require additional components, components with higher cost, or higher quiescent current which results in lower efficiency.

The LT3081HT7#PBF Linear Regulator provides an output voltage range of 0.8V to 5.5V, with a maximum output current of 5A, and an input voltage range of 2.2V to 6V. The device also features a wide-temperature range operation from -40C to +125C.

Applications

The LT3081HT7#PBF is an ideal device for various applications, including power supplies, battery-powered systems, ASIC and DSP power supplies, automotive power management, and industrial and consumer applications where precision and load regulation is required.

In addition, its small physical size and low quiescent current make it simple to integrate into any project where power management is critical. The device is also suitable for a wide range of other applications such as automotive, medical, communications, and consumer electronics.

Working Principle

The LT3081HT7#PBF is an adjustable regulator, meaning it operates on the same principles as a fixed output regulator, but the output voltage is adjustable via an external reference voltage.

The voltage regulator consists of two main parts, the error amplifier and the output stage. The error amplifier is used to compare the error signal from the output to the externally supplied reference voltage. If this error signal exceeds the reference voltage, the output stage will reduce or increase the output voltage accordingly to bring the output voltage back into a predetermined voltage range.

The LT3081HT7#PBF also uses a Power Sense Pin, which is used to monitor the current out of the regulator. This pin is connected to the external power source, and signals the regulator whether the output current exceeds the specified maximum current. If it does, the device will reduce its output current accordingly.

The device also features a thermal protection circuit, which is used to protect the device against possible thermal overload due to abnormal operation conditions. The thermal protection circuit can be disabled if not needed.

With its low-noise, low-drop-out performance, and high-load capability, the LT3081HT7#PBF linear voltage regulator is an ideal choice for a wide range of applications that require precision and power management.
