LT3048 Series Low Noise Bias Generator
in 2mm × 2mm DFN
DESCRIPTION
The LT®3048 series generate low noise, low ripple bias supplies from input voltages of 2.7V to 4.8V. The LT3048 includes a boost
regulator and a LDO linear
regulator. The boost
regulator provides power to the linear
regulator. The boost
regulator output voltage is regulated to 1.1V above the LDO output, optimizing LDO ripp...
