Introduction

AI Translation

The ±3048 series generates low noise, low ripple bias supplies from 2.7V to 4.8V input voltage. The LT3048 includes a boost regulator and an LDO linear regulator. The boost regulator powers the linear regulator. The boost regulator output voltage is regulated to 1.1V above the LDO output to optimize the LDO's ripple rejection and transient response. Fixed frequency operation and current mode control allow the use of very small inductors and produce low, predictable output ripple. The linear regulator in the LT3048 generates a programmable output, while the LT3048-xx generates a fixed output voltage. High power supply ripple rejection combined with a low noise internal reference keeps output ripple and noise below 500µVP-P. The LT3048 is available in an 8-lead 2mm × 2mm DFN package.
