Overview
Description
The ISL75051SRHEVAL1Z evaluation board provides a simple platform to evaluate the performance of the ISL75051SRH radiation hardened low dropout linear regulator (LDO).
The ISL75051SRH is a high-performance, adjustable, low-voltage, high-current, low dropout linear regulator specified at 3A rated output current for input voltages from 2.2V to 6V. The LDO's output can be adjusted from 0.8V to 5V using two preset resistors.
Features
- TID, ELDRS and SEE rated
- Very fast load transient response
- ±2.0% guaranteed VOUT accuracy over line, load and temperature
- Typical dropout of 287mV at 3A
- EN, PG and OCP features
- Short-circuit and over-temperature protection
Applications
Applications
- LDO regulators for space applications
- DSP, FPGA and microprocessor core power supplies
- Post-regulation of switched mode power supplies
- Down-hole drilling

Josh Broline discusses the FPGA reference design featuring the ISL70001SEH, ISL70002SEH, and ISL75051SRH radiation hardened products at APEC 2013.
Transcript
Hello from APEC 2013 here in Long Beach, CA. My name is Josh Broline, I'm the product marketing manager for Space and High reliability products group here at Intersil. Here we are demoing Intersil's FPGA reference design, specifically for Xilinx. We have three point-of-load regulators, the ISL70001SEH, which is a 6A regulator. Also, we have the ISL70002SEH, which has an output of 12A. It can also be powered off of a 3.3V or 5V rail. And last, we have the ISL75051, which is a 3A, low dropout regulator. It has superior dropout performance. For example, at 65mV at 1.5A, or about 225mV at 3A. I would actually put this product up specifically next to a commercial type product.
The critical thing to know about these particular products is that we did specific roundup designs to ensure that these products would survive the space and harsh environments. For example, we have single event transient immunity within plus or minus 1%. So if you have a stack up say at plus or minus 5%, that is absolutely critical very tight performance, whether it be at single event transient over radiation and all the different conditions that you would run into. For more information, you can go to the Space and Harsh Environments product page on our website. We have reference designs, application notes. You can get schematics and layout files or you can find more information on these particular products. Also, you can go to the specific product information pages for each individual product.
