Overview

The ISL75054SLHEVAL1Z evaluation board provides a quick and efficient way to evaluate the performance and features of 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 (V_IN - V_DO), 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.
