Applications

LT3065EDD-1.2#TRPBF is applicable to a wide range of applications, such as handheld devices, wireless technology, digital cameras, cell phones, automotive and industrial devices. Its adjustable output voltage range is 2.5V~28V and can be regulated to a voltage as low as 0.615V with a precision of ±2.5%.LT3065EDD-1.2#TRPBF can be used for development of battery operated systems, as it provides low quiescent current and low output voltage ripple. It can prevent reverse current from the input AC power supply from entering the battery, which helps to extend the battery life. Enterprises normally use this regulator for their power management systems, such as their quality system, manufacturing system, and storage system.

Working Principle

LT3065EDD-1.2#TRPBF works in the linear mode. Its output voltage is controlled and tracked by the feedback signal generated by the voltage divider. A difference amplifier compares the feedback signal with a reference voltage, generating an adjustment command. The adjustment command is then sent to a p-channel MOSFET and the current on it is regulated by the PWM signal, working as a constant current source. The current of the P-channel MOSFET is then fed back to the input, setting a stable output voltage.

Conclusion

LT3065EDD-1.2#TRPBF is an ideal low voltage linear regulator, being economical and adjustable, with excellent performance and low output noise. It is suitable for many applications, such as handheld devices, wireless technology, digital cameras, cell phones, automotive and industrial devices, and has great utilization values. The working principle of LT3065EDD-1.2#TRPBF is by connecting the p-channel MOSFET to the input power supply, the current on it is regulated by the PWM signal and will be fed back to the output, setting a stable output voltage.
