描述
The ISL75054SLHDEMO1Z demonstration board provides a quick and easy method for evaluating the ISL75054SLH, an ultra-low noise, high-PSRR, radiation hardened low-dropout regulator (LDO) ideal for powering sensitive analog loads such as RF devices and ADCs.
The ISL75054SLH supports a wide input voltage range of 2.7V to 30V, with an adjustable output from 0.5V up to (VIN - VDO), and can source up to 1A of output current. Key features include adjustable soft-start, an open-drain power-good indicator, and over/undervoltage detection to monitor output status.
Built-in protections such as over-temperature shutdown and internal and resistor-adjustable current limiting with foldback enhance system reliability. The integration of a precision internal current source and high-performance voltage buffer error amplifier enables ultra-low output noise and high PSRR, while minimizing the number of external components required, reducing BOM, solution size, and design complexity.
For information about the device operation, function, and performance, refer to the ISL75054SLH datasheet.
