Description

The AW37023 is a low-noise (5μVrms), low-dropout linear regulator capable of sourcing 3A with only 160mV of maximum dropout. The combination of low noise, high PSRR, and high output current capability makes the AW37023 an excellent choice to power noise-sensitive components, such as those found in radar power and infotainment applications. The AW37023 output voltage is pin-programmable from 0.8V to 3.95V, and adjustable from 0.8V to 5.2V using an external resistor divider. The high performance of the AW37023 limits power supply generated phase noise and clock jitter, making the AW37023 ideal for powering RF amplifiers, radar sensors, and chipsets. Specifically, RF amplifiers benefit from the high-performance and 5.0V output capability of the device. For digital loads such as application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), and digital signal processors (DSPs) that require low-input, low-output (LILO) voltage operation, the exceptional accuracy (±1%), remote sensing, excellent transient performance, and soft-start capabilities of the AW37023 provide optimal system performance.
