Frequently Asked Questions
What is the input voltage operating range for the RHFL4913ESY2506V, and how does it compare to commercial regulators?
The RHFL4913ESY2506V operates from an input voltage of 5 V to 12 V, with an absolute maximum of 14 V, covering typical satellite power bus ranges. Unlike commercial LDO regulators, this device is radiation-hardened to maintain its fixed output and 0.95 V dropout voltage without degradation after cumulative TID exposure in orbital environments.
How precise is the voltage regulation of the RHFL4913ESY2506V under varying loads?
The RHFL4913ESY2506V achieves a maximum load regulation of 0.01% and a maximum line regulation of 0.01%, delivering exceptional output stability across load and input variations. This level of precision is essential for powering analog-to-digital converters, reference circuits, and precision sensors aboard scientific satellite payloads where supply noise directly impacts measurement accuracy.
For which orbital mission profiles is the RHFL4913ESY2506V best qualified?
The RHFL4913ESY2506V is best qualified for LEO, MEO, and GEO satellite missions where total ionizing dose radiation from protons and electrons is a primary reliability concern. Its radiation-hardened vertical TO package tolerates the extended thermal cycling between -55°C and +125°C typical of spacecraft power subsystems, and its fixed output removes the need for external trim resistors that could drift under radiation exposure.
