LT3048-15 Datasheet

LT3048-15 Low Noise Bias Generator

The LT®3048-15 generates a low noise, low ripple bias supply from an input voltage of 2.7V to 4.8V. The LT3048-15 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 o.
