Working principle

The LT3066EMSE-5#PFB operates on a classic linear regulator circuit topology, comprising a pass device and its associated input, feedback, and output circuitry. It employs an internal P-channel MOSFET pass transistor, which allows the device to achieve improved dropout performance (the amount of input power required beyond what is required to supply the output) over conventional linear regulator topologies.

The device is designed to regulate the output voltage relative to the “REFIN” pin, which has an internal voltage reference. The device employs an adjustable negative voltage output, allowing the user to specify the desired output voltage by adjusting this voltage. The user can also select the output current, which is adjusted through the use of a sense resistor placed in series with the output. The output voltage is monitored and feedback is used to drive the pass transistor’s gate voltage, enabling the device to maintain the specified output voltage. The device also features an under-voltage lockout and current limit circuit, which ensure safe operating conditions.

Conclusion

The LT3066EMSE-5#PFB is a versatile, industrial-grade ultra-low-dropout linear regulator for use in a variety of power management, RF signal conditioning, bridging interface circuits, and other applications. Its class-leading capabilities, low dropout performance, and comprehensive protection mechanisms make it an ideal choice for mobile device, RF, power conversion, and other applications.
