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 output, optimizing LDO ripple rejection and transient response.
Fixed frequency operation and current mode control allow the use of ve...
