Key Features
- 3.3 V nominal input (2.97 V to 3.63 V) directly compatible with standard 3.3 V logic supply rails
- Single-output unregulated DC-DC conversion in a compact SIP-4 package for minimal PCB footprint
- Up to 10% load regulation enabling use in non-precision auxiliary rail applications
- REACH-compliant construction supporting RoHS and green design requirements in industrial end products
Applications
The RO-3.324S is designed for board-level power conversion in embedded systems and industrial I/O modules where the main 3.3 V bus must supply a secondary auxiliary rail without a complex regulated converter. Its SIP-4 through-hole package simplifies integration onto industrial PCBs that need a small isolated or unregulated output from the 3.3 V system rail. The module suits sensor node power trees, signal conditioning circuits, and low-power relay driver supply rails where a 10% load regulation tolerance is acceptable.

Frequently Asked Questions
What input voltage range does the RO-3.324S accept and how does this align with standard 3.3 V logic supply tolerances?
The RO-3.324S accepts an input voltage from 2.97 V to 3.63 V, which corresponds exactly to the ±10% tolerance window around a 3.3 V nominal rail. This means it can be powered directly from a regulated 3.3 V bus without additional input filtering or pre-regulation, simplifying the power tree design in embedded systems with a single 3.3 V main supply.
How does the RO-3.324S's 10% load regulation specification affect its suitability for precision analog circuits?
The RO-3.324S has a maximum load regulation of 10%, meaning the output voltage can shift by up to 10% as the load current varies from no-load to full-load conditions. This level of regulation is acceptable for auxiliary digital rails, relay drivers, or LED supplies, but it is not suitable for powering precision ADC references or op-amp rails that require tighter than 1% regulation without an additional LDO post-regulator.
What is the physical package format of the RO-3.324S and how does it simplify PCB integration?
The RO-3.324S is housed in a SIP-4 (single in-line package with 4 pins) through-hole format, which uses a 2.54 mm pin pitch compatible with standard PCB drill patterns. This allows the module to be hand-soldered or wave-soldered onto industrial PCBs without specialized SMD equipment, and the module body stands vertically to minimize the PCB footprint to roughly 12 mm x 6 mm board area.
In which embedded or industrial applications does the RO-3.324S provide the best fit as a power module?
The RO-3.324S is best suited for applications powered from a 3.3 V bus that need a secondary rail for relay coils, optocoupler drives, or isolated sensor interfaces, where the 10% load regulation and single-output topology are acceptable. Industrial I/O cards, PLC expansion modules, and RS-485 or CAN transceiver supply rails operating within the 2.97 V to 3.63 V input window are typical use cases.
