The LT3066EDE is a 45V VIN, 500mA low-noise, linear regulator with programmable current limits and active output discharge function launched by (ADI). The following is a detailed introduction to the LT3066EDE

The LT3066EDE is a low-power, low-noise, low-dropout voltage (LDO) linear regulator that operates within an input voltage range of 1.8V to 45V. In addition, the LT3066EDE can provide an output current of 500mA and a typical differential voltage of 300mV. A single external capacitor provides programmable low-noise benchmark performance and output soft-start functionality.

The LT3066EDE uses a single resistor to set the current limit of the LT3066 and can achieve an accuracy of ±10% over a wide range of input voltages and temperatures. A PWRGD tag is used to indicate output regulation.

The LT3066EDE features a pull-down NMOS, which is responsible for discharging the output when the SHDN or IN is driven to a low level.

The LT3066EDE optimizes stability and transient response by using low ESR ceramic capacitors, with a minimum required capacitance of 3.3μF. The internal protection circuit includes current limit with return, thermal limit, reverse battery protection, reverse current protection and reverse output protection.

The LT3066EDE features available fixed output voltages of 3.3V and 5V, and can be used as an adjustable device with an output voltage range of 0.6V to 19V. This device features a heat-resistant performance enhanced 12-pin 4mm x 3mm DFN and MSOP package.
