Frequently Asked Questions
What input voltage range and dropout voltage does the RHFL4913ESY2505V support?
The RHFL4913ESY2505V accepts input voltages from 5 V minimum to 12 V maximum, with an absolute maximum rating of 14 V. Its typical dropout voltage is 0.95 V, so a 5.95 V or higher input is needed to maintain regulation at the fixed 5 V output. Line and load regulation are both specified at 0.01% maximum for precision power delivery.
For which radiation-hardened space applications is the RHFL4913ESY2505V best suited?
This regulator is ideal for satellite on-board computers, attitude control electronics, and payload power conditioning boards that require a stable 5 V rail immune to total ionizing dose and single-event latch-up effects. The TO-3 metal package provides additional thermal dissipation and mechanical robustness required in space-qualified assemblies operating under extreme environmental conditions.
How does the RHFL4913ESY2505V package compare to plastic-packaged regulators for thermal management?
The R-CSFM-T3 (TO-3 metal) package of the RHFL4913ESY2505V offers superior thermal conduction compared to plastic TO-220 or TO-252 packages, enabling effective heat sinking to chassis structures common in spacecraft enclosures. Its vertical lead configuration allows direct mounting to baseplate heat spreaders, supporting thermal dissipation in vacuum environments where convection is absent.
