Frequently Asked Questions
What input voltage range and dropout voltage does the RHFL4913ESY5005V support?
The RHFL4913ESY5005V accepts an input voltage range of 7.5 V to 12 V with an absolute maximum of 14 V. Its nominal dropout voltage is 0.3 V, enabling efficient operation even when the input is close to the regulated output. These parameters make it well suited for space power buses where input voltage can fluctuate over the mission lifetime.
How does the RHFL4913ESY5005V's line and load regulation compare to commercial regulators for satellite designs?
The RHFL4913ESY5005V achieves 0.02% maximum line regulation and 0.02% maximum load regulation, which is significantly tighter than most commercial LDOs that typically specify 0.1% to 0.5%. This precision is critical for satellite analog signal chains and ADC reference supplies where supply variation of even a few millivolts can degrade measurement accuracy over a multi-year mission.
What package does the RHFL4913ESY5005V use and how does it affect board-level integration in space hardware?
The RHFL4913ESY5005V is housed in a vertical transistor outline (TO) hermetic package with JESD-30 code R-CSFM-T3. This hermetically sealed metal package is standard in space-qualified assemblies, offering protection against outgassing and cosmic ray induced latch-up while meeting the mechanical requirements of through-hole mounting used in radiation-hardened PCB stacks on spacecraft.
