What are the key features of RHFL4913ESY1506V?
- Radiation-hardened design for space and high-radiation environments with guaranteed performance under particle flux
- Ultra-low line and load regulation of 0.006% maximum for precision 1.5 V supply in sensitive analog circuits
- Low dropout voltage of 0.95 V nominal enabling 1.5 V output from input voltages as low as 3 V
What is RHFL4913ESY1506V used for?
The RHFL4913ESY1506V is engineered for satellite subsystems, space instruments, and radiation-exposed military avionics requiring a stable 1.5 V regulated supply under ionizing radiation conditions. It powers radiation-sensitive digital logic, memory arrays, and analog processing circuits in LEO and GEO satellite platforms where commercial regulators would fail due to total ionizing dose effects. Its 3 V to 12 V input range accommodates common space bus voltages while maintaining tight output regulation throughout the mission lifetime.

Frequently Asked Questions
What is the input voltage range of the RHFL4913ESY1506V, and what space bus voltages does it support?
The RHFL4913ESY1506V accepts input voltages from 3 V to 12 V with an absolute maximum of 14 V, supporting common satellite power bus rails at 3.3 V, 5 V, and 12 V. This wide input range allows a single regulator design to accommodate variations in bus voltage during eclipse and sunlight orbital phases.
How tight are the line and load regulation specifications of the RHFL4913ESY1506V for precision analog circuits?
Both line and load regulation of the RHFL4913ESY1506V are specified at 0.006% maximum, meaning output voltage variation is held to less than 0.1 mV across input and load changes. This level of regulation is critical for powering precision ADCs, DACs, and reference circuits in satellite scientific instruments where power supply noise directly affects measurement accuracy.
What is the dropout voltage of the RHFL4913ESY1506V, and why does it matter in low-power satellite designs?
The RHFL4913ESY1506V has a nominal dropout voltage of 0.95 V, which means it maintains the 1.5 V regulated output from an input as low as approximately 2.45 V under ideal conditions. Low dropout operation is essential in satellite power budgets where every milliwatt saved reduces solar panel size and thermal dissipation requirements in vacuum.
Is the RHFL4913ESY1506V packaged in a hermetic enclosure suitable for space-grade assembly?
Yes, the RHFL4913ESY1506V is housed in a ceramic SIP-3 (CSIP-T3) package, which provides hermetic sealing to prevent moisture ingress and outgassing in space vacuum environments. Ceramic packages are mandatory for Class K space-grade component assembly per MIL-PRF standards and support lead-frame soldering at temperatures consistent with space-grade PCB processes.
