Key Features
- Unregulated single-output DC-DC converter with 15 V nominal input and 5 V output for simple point-of-load conversion
- Wide input voltage range of 13.5 V to 16.5 V accommodating standard 15 V bus variations without external components
- SMA package enabling direct PCB through-hole mounting for robust mechanical attachment in vibration-prone environments
- Up to 15% load regulation suitable for non-critical supply rails powering logic circuits and sensors
- REACH-compliant construction meeting European chemical substance regulations for global market deployment
Applications
The ROE-1505S is used in distributed power systems where a 15 V primary bus must feed 5 V logic or sensor supply rails without a tight regulation requirement. It suits industrial instrumentation, signal conditioning cards, and legacy telecom equipment that already carry a 15 V supply and need a low-cost 5 V derived rail. Its compact SMA footprint also makes it appropriate for space-constrained backplane sub-modules and auxiliary power circuits.

Frequently Asked Questions
What input voltage range does the ROE-1505S accept and how much headroom exists above and below the nominal 15 V?
The ROE-1505S accepts an input voltage range of 13.5 V to 16.5 V, providing 1.5 V of headroom below and above the nominal 15 V rail. This ±10% tolerance accommodates standard bus regulation variations found in industrial 15 V power supplies without requiring additional filtering or pre-regulation stages before the module input.
What is the load regulation specification of the ROE-1505S and which application types can tolerate it?
The ROE-1505S has a maximum load regulation of 15%, meaning the 5 V output can vary by up to 0.75 V between no-load and full-load conditions. This level of regulation is acceptable for powering non-critical analog sensor front ends, indicator LEDs, relay coils, and legacy TTL logic circuits that can tolerate output swings within 4.25 V to 5.75 V without affecting functionality.
What package type does the ROE-1505S use and how does it mount on a PCB?
The ROE-1505S uses an SMA through-hole package with 4 pins on a standard pitch, allowing wave soldering or hand soldering directly onto PCB pads. The through-hole termination provides superior mechanical retention compared to SMT pads, making it preferable for industrial equipment subject to vibration or thermal cycling where solder joint fatigue is a concern.
How does the ROE-1505S fit into a 15 V distributed power architecture versus using a linear regulator for 5 V conversion?
The ROE-1505S eliminates the 10 V dropout dissipation inherent to a linear regulator converting 15 V down to 5 V, which would waste 200 mW at 20 mA load as heat. As a DC-DC module it converts power more efficiently, reducing heatsinking requirements and board temperature rise in enclosures with limited airflow, though its 15% load regulation is looser than a typical linear regulator's 1-2%.
Is the ROE-1505S REACH compliant and what does that mean for product certification?
Yes, the ROE-1505S carries REACH Compliance status, confirming it does not contain substances of very high concern (SVHC) above 0.1% by weight as defined by EU Regulation 1907/2006. This allows the end product to be sold into the European Union market without requiring an SVHC declaration, simplifying RoHS and REACH documentation audits during CE marking and system-level environmental compliance certification.
