LT3022EDHC#PBF is an adjustable low dropout linear regulator. It takes 4.5V to 18V input voltage, and provides output voltage up to 3V with an adjustable output voltage range of 0.6V to 3V. This device is featured by low quiescent current, low power operation in low voltage dropout region and fast transient response, as well as temperature stability. The LT3022EDHC#PBF application field includes applications such as battery powered portable system, 3V logic supply, LCD monitor, multimedia notebook, touch panel, audio power amplifier and USB power supply. Along with a low temperature coefficient and a low dropout voltage operating range, combined with low quiescent current, this device provides an efficient power solution for systems with tight supply voltage and current requirements. LT3022EDHC#PBF can be used in two different types of operation mode: Shutdown mode and Fixed Output Voltage mode. In Shutdown mode, the regulator will completely shut down and provide 0uA current to the output, making it an ideal solution for reducing power consumption in applications with high power demand. In Fixed Output Voltage mode, the LT3022EDHC#PBF can be used to provide a low dropout and low power linear output voltage in the specified range (0.6V to 3V). The LT3022EDHC#PBF has two types of stabilized output voltage control: four resistors winding voltage control and feedback pin voltage control. The winding voltage control method can adjust the output voltage by the ratio of four selectable resistors. The feedback pin voltage control method can adjust the output voltage by setting the voltage of the feedback pin. These two voltage control methods are not mutually exclusive, and can be used jointly. In addition, LT3022EDHC#PBF provides a maximum output current limit. By setting the current sense resistor between the ground and the output terminal of the regulator, the current limit of the regulator can be adjusted from 0.2A to 1A. In addition, the multiple output voltage sensing modes also make the device can be used in applications with multiple power domains or different power output requirements.LT3022EDHC#PBF also includes input voltage, thermal and output voltage protection. The device has an under voltage lockout protection circuit which monitors the input voltage and shuts down the regulator when the input voltage falls below the minimum limit. The device also has thermal limit and output overvoltage protection which can protect the device and circuits from overcurrent and overvoltage conditions by limiting the output current or voltage to a safe level. In conclusion, LT3022EDHC#PBF is an adjustable low dropout linear regulator with high performance and low power operation, making it an ideal choice for a variety of applications. Its adjustable output voltage range and multiple output voltage sensing modes make the device suitable for applications with multiple power domains or different power output requirements. Its high precision and low dropout features make it an excellent solution for applications with tight supply voltage and current requirements.
