Frequently Asked Questions
What dropout voltage and PSRR performance can designers expect from the LT3045IMSE#TRPBF in RF supply designs?
The LT3045IMSE#TRPBF achieves a typical dropout voltage of 0.22V and a maximum of 0.45V at 500 mA, alongside ultralow output noise and ultrahigh PSRR, making it an excellent choice for powering RF synthesizers, VCOs, and LNAs where power supply noise directly impacts phase noise and spurious performance.
How does the adjustable output and 0.0033% load regulation of LT3045IMSE#TRPBF benefit precision ADC power supply designs?
The adjustable output allows the LT3045IMSE#TRPBF to be set to 1.2V, 1.8V, 2.5V, or 3.3V rails needed by high-resolution ADCs, while its 0.0033% maximum load regulation ensures output voltage remains stable across varying current loads from 1 mA to 500 mA, preserving ADC dynamic range and minimizing supply-induced measurement error.
Can multiple LT3045IMSE#TRPBF devices be paralleled to increase output current beyond 500 mA?
Yes, the LT3045IMSE#TRPBF is designed to parallel multiple devices for output currents exceeding 500 mA by connecting output and SET pins together. This feature, combined with the 20V maximum input and ultralow noise characteristic, allows designers to scale supply current from 500 mA up to several amperes in high-current RF and instrumentation applications without degrading noise or PSRR.
