For details

The LT3045EMSE is designed as a precision current reference voltage source for subsequent high-performance voltage buffers. It can be easily connected in parallel to further reduce noise, increase output current and dissipate heat on the PCB.

The LT3045EMSE provides a current of 500mA at a typical voltage difference of 260mV. The nominal working static current is 2.2mA, and it drops to less than 1µA when turned off. The LT3045EMSE features a wide output voltage range (0V to 15V) while maintaining unit gain operation, providing almost constant output noise, PSRR, bandwidth and load adjustment performance, unaffected by the programmed output voltage. In addition, the LT3045EMSE features programmable current limiting, fast startup capability, and a well-programmed power supply to indicate output voltage regulation.

The LT3045EMSE can operate stably with ceramic output capacitors as small as 10µF. The built-in protection functions include battery reverse connection protection, reverse current protection, internal current limiting with return function and thermal limiting with hysteresis. The LT3045EMSE adopts a heat-enhanced 12-pin MSOP package.
