Frequently Asked Questions
What is the maximum output current the LT1521CMS8#PBF can supply, and what dropout voltage should designers expect at full load?
The LT1521CMS8#PBF delivers up to 300 mA of output current. At full load, the typical dropout voltage is 0.5 V and the maximum is 0.75 V, enabling efficient regulation even when the input-to-output differential is small.
For a battery-powered sensor node running from a Li-ion cell, how suitable is the LT1521CMS8#PBF as a power regulator?
The LT1521CMS8#PBF handles input voltages up to 20 V and delivers 300 mA with a dropout of only 0.5 V typical, making it suitable for single-cell Li-ion applications. Its adjustable output and low quiescent current help extend battery runtime in sensor nodes.
How does the LT1521CMS8#PBF achieve its lead-free compliance, and which package does it use?
The #PBF suffix indicates RoHS-compliant, lead-free construction using a JESD-609 e3 process. The device is housed in an 8-pin MSOP package (JESD-30 code S-PDSO-G8), occupying minimal PCB area while supporting 300 mA regulated output.
What load and line regulation specifications make the LT1521CMS8#PBF appropriate for precision analog circuits?
With maximum line regulation of 0.033 %/V and maximum load regulation of 1.4 %, the LT1521CMS8#PBF maintains a stable output voltage across varying input and load conditions, making it suitable for precision analog front-ends, data converters, and sensor bias supplies.
