Frequently Asked Questions
What is the input voltage range and output current capability of the LT3066EMSE-3.3#PBF?
The LT3066EMSE-3.3#PBF operates from 3.9 V to 45 V input and supplies up to 500 mA output current at a fixed 3.3 V regulated output, making it suitable for a wide range of industrial power supply designs.
How does the programmable current limit feature benefit motor driver or sensor power supply designs?
The programmable current limit allows designers to set a maximum current threshold below 500 mA, protecting downstream sensors or actuators from overcurrent damage. This is especially valuable in 12 V or 24 V industrial systems where load protection is critical.
What is the typical dropout voltage of the LT3066EMSE-3.3#PBF and why does it matter for battery-powered applications?
The LT3066EMSE-3.3#PBF has a typical dropout voltage of 300 mV at full 500 mA load. This low dropout allows the regulator to maintain 3.3 V output even when the supply voltage drops close to the output level, extending battery runtime in portable equipment.
