The LT3060EDC-15#TRMPBF has a good working principle and its main function is to regulate and deliver desired output voltage as a power supply with very low output ripple and noise. It can work efficiently within its given input voltage range while providing accurate and clean output voltage. The device uses a low dropout linear regulator architecture to achieve its high efficiency and low noise. This Linear Voltage Regulator is designed to sense an input voltage of 3V to 24V and provide an adjustable output voltage range of 1.24V to 20V.

Operation Description

When an input voltage is applied to the device, a low dropout linear regulator starts to work. The internal control circuit controls the gate voltage of the P-MOSFET to regulate and deliver the output voltage as required. During operation, the output current and voltage are sensed, and the internal control circuit adjusts the voltage applied to the gate of the MOSFET to ensure the the required output voltage is delivered to the power rail. When the output voltage drops, the internal control circuit turns on the P-MOSFET for longer time, lowering the voltage of the power rail. When the output voltage rises, the internal control circuit turns off the P-MOSFET for longer time, increasing the voltage of the power rail.

The LT3060EDC-15#TRMPBF is designed to operate in the drop-out region. It efficiently monitors the output voltage by comparing the reference voltage of the voltage divider with the sensed voltage and adjusts the conduction time of the P-MOSFET accordingly.

Conclusion

The LT3060EDC-15#TRMPBF is a member of the Linear PMIC - Voltage Regulators family. This Voltage Regulator is a high-efficiency, ultra-low-noise voltage regulator designed for input voltage of 3V to 24V and adjustable output voltage range of 1.24V to 20V. It provides a greater level of efficiency, due to its low dropout linear regulator architecture, and an ultra-low noise level for precision analog and audio applications.
