Overview

Description

The ISL75054MDEMO1Z demonstration board showcases the ISL75054M, an ultra-low noise, high-PSRR, radiation tolerant low-dropout regulator (LDO) ideal for powering sensitive analog loads such as RF devices and ADCs.

The ISL75054M 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 an adjustable soft-start, an open-drain power-good indicator, and overvoltage/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.

The ISL75054MDEMO1Z offers a straightforward way to evaluate the functionality and performance of the ISL75054M in a compact layout. For detailed specifications and application guidance, refer to the ISL75054M datasheet.
