What are the key features of RHFL4913ESY5006V?
- Radiation-hardened design withstands total ionizing dose (TID) environments encountered in LEO and GEO satellite power regulation applications
- Ultra-tight 0.02% line regulation and 0.02% load regulation with 0.3 V dropout voltage ensure stable supply rails for sensitive analog and digital space payloads
- Hermetic TO-3 vertical metal package (R-CSFM-T3) provides robust mechanical protection and thermal dissipation for high-reliability space and military power systems
What is RHFL4913ESY5006V used for?
RHFL4913ESY5006V is used in satellite on-board power conditioning units and spacecraft electronics requiring a radiation-tolerant fixed voltage regulator for analog subsystems and microcontroller supply rails. The 7.5 V to 12 V input range and 0.3 V dropout voltage suit regulated bus architectures in LEO and GEO platforms where total ionizing dose exceeds standard commercial device limits. Its hermetic TO-3 package also addresses military avionics and nuclear-hardened ground systems demanding long-term reliability under extreme environmental stress.

Frequently Asked Questions
What input voltage range and dropout voltage does RHFL4913ESY5006V support?
RHFL4913ESY5006V accepts an input voltage from 7.5 V to 12 V with an absolute maximum of 14 V, and operates with a 0.3 V typical dropout voltage. This low dropout margin allows the regulator to maintain its fixed output even when the spacecraft bus voltage sags near the minimum under peak load conditions.
How does the radiation hardening of RHFL4913ESY5006V benefit satellite power designs?
RHFL4913ESY5006V is radiation-hardened to withstand the total ionizing dose (TID) levels typical of LEO and GEO orbital environments, preventing parametric shifts in line regulation beyond 0.02% that would destabilize sensitive scientific instrument supply rails. Commercial regulators can fail or drift by several percent under even 10 krad(Si), while rad-hard parts like RHFL4913ESY5006V maintain stable 5 V output throughout mission lifetimes of 5 to 15 years.
Why is the hermetic TO-3 package (R-CSFM-T3) specified for RHFL4913ESY5006V rather than a plastic package?
The hermetic TO-3 (R-CSFM-T3) metal package of RHFL4913ESY5006V seals the die against vacuum outgassing, moisture, and particle contamination that would degrade plastic-packaged devices in space or high-reliability military environments. The metal case also provides an effective thermal path for dissipating regulator heat when input-to-output differential spans the full 12 V input range, supporting higher continuous output current than compact SMT alternatives.
