ADP5073ACPZ-R7

ADP5073 is a high performance DC to DC inverting regulator used to generate negative supply rails. The input voltage range of 2.85 V to 15 V supports a wide variety of applications. The integrated main switch enables the generation of an adjustable negative output voltage down to 39V below the input voltage. It can synchronize with an external oscillator from 1MHz to 2.6MHz to ease noise filtering in sensitive applications. The regulator implements programmable slew rate control circuitry for the MOSFET driver stage to reduce electromagnetic interference (EMI). It includes a fixed internal or resistor programmable soft start timer to prevent inrush current at power-up. During shutdown, the regulator completely disconnects the load from the input supply to provide a true shutdown. It is used in application such as bipolar amplifiers, ADCs, digital-to-analog converters (DACs), and multiplexers, high speed converters, radio frequency (RF) power amplifier (PA) bias, optical modules etc.
