Working Principle

The LT3091IDE#TRPBF is a low-voltage adjustable linear regulator that provides a regulated output voltage over a wide input voltage range. The regulator employs a Linear Technology proprietary, on-chip architecture which accurately regulates the voltage of the output node. The output voltage is adjustable over a wide range, with a settling time of less than 100μs. A feedback resistor (RF) is connected between the OUT terminal of the chip and Ground, which sets the output current.

The LT3091IDE#TRPBF also features integrated feedback compensation, over-current protection, and adjustable soft-start. The device utilizes a P-channel MOSFET, connected to the OUT terminal, where the current flowing through the MOSFET is varied in order to regulate the output voltage. The regulation loop senses the output voltage, and adjusts the MOSFET current accordingly to maintain a constant output voltage.

Conclusion

The LT3091IDE#TRPBF is a low-voltage adjustable linear regulator that can operate with input voltages greater than its output voltage. It provides a regulated output voltage with a wide adjustable range, low quiescent current, and guarantee line and load regulation over a wide input voltage and output voltage range. The LT3091IDE#TRPBF is suitable for use in many high power and low power applications, including battery management systems, light dimmers, and system power supplies.
