With an input voltage range of 1.8V to 20V and an adjustable output from 1.22V to 20V, it provides up to 500mA output current while maintaining ultra-low output noise of only 20\u03bcVRMS over the 10Hz to 100kHz bandwidth. The device draws only 30\u03bcA quiescent current during normal operation and less than 1\u03bcA in shutdown mode, making it ideal for battery-powered systems. The LT1763 features reverse battery protection, current limit with foldback, and thermal shutdown for robust operation in demanding environments.","working_principle":"The LT1763 operates as a series-pass linear regulator with three key subsystems. (1) The bandgap reference generates a precision 1.22V reference voltage that is compared against a divided-down version of the output voltage by the error amplifier. The feedback network (external resistors) sets the desired output voltage between 1.22V and 20V. (2) The series-pass PNP transistor regulates current flow from IN to OUT, controlled by the error amplifier to maintain the output at the set voltage. The PNP architecture enables low dropout voltage of 300mV at full 500mA load. (3) The noise reduction subsystem includes an internal noise filtering network and a reference bypass pin (BYP) that allows an external capacitor to further reduce reference noise, achieving the ultra-low 20\u03bcVRMS output noise specification.","pin_description":"
