ADP5071ACPZ-R7

ADP5071 is a dual high performance dc-to-dc regulator that generates independently regulated positive and negative rails. The input voltage range of 2.85V to 15V supports a wide variety of applications. The integrated main switch in both regulator enables generation of an adjustable positive output voltage upto +39V and a negative output voltage down to −39V below input voltage. This regulator implements programmable slew rate control circuitry for the MOSFET driver stage to reduce electromagnetic interference (EMI). This device includes a fixed internal or resistor programmable soft start timer to prevent inrush current at power-up. During shutdown, both regulators completely disconnect the loads from the input supply to provide a true shutdown. It is widely used in application such as bipolar amplifiers, ADCs, DACs, and multiplexers, charge-coupled device (CCD) bias supply, optical module supply, RF power amplifier (PA) bias etc.
