This slide highlights some of the LT3042’s key features and benefits. High power supply ripple rejection of 79 dB at 1 MHz is included for noise supply rejection and reduction of output ripple. Low output voltage noise, 0.8 µVrms, and low spot noise of 2nV/√Hz at 10 kHz generate a clean supply for sensitive radio frequency applications. A precision 100 µA current source reference allows output voltage operation down to 0 V. It has the ability to directly parallel ICs without an op amp, reduces output errors and susceptibility to poor PCB cleaning, and offers excellent accuracy over temperature performance with nearly “0” temperature coefficient. The LT3042 features high Vout accuracy of ±1% for use in precision power supplies; a single resistor programs output voltage for ease of design. The output voltage equals the reference current multiplied by the resistor value. Outputs may be easily and directly paralleled which offers a higher-current capability than a single regulator may provide; plus it spreads heat across a PCB as well as further reduces noise. The wide input voltage range of 1.8 V to 20 V which offers flexibility, works well in systems where multiple voltage rails are needed and used and allows direct conversion from 12 V system rails, eliminating an intermediate switching regulator stage, thus saving board space and simplifying design. Also featured is an adjustable output voltage range of 0 V to 15 V. Providing a wide range of outputs, the minimum output voltage can be adjusted below 1.2V with no circuit tricks. The low dropout voltage of 350 mV reduces power dissipation. Fast startup capability and programmable precision current limit, which allows the user to set current limit as low as 115% of maximum load without affecting normal operation load regulation, are included. This reduces upstream power supply output current requirements. The device also has reverse battery, current, and output-to-input protections, and thermal limiting. It is available in small DFN and MSOP packages which provide a good amount of current in a small footprint with great thermal performance.
