What are the key features of IZ0503SA?
- Wide 4.5 V to 9 V input range accommodating 5 V and 9 V bus rails with single 3.3 V regulated output (3.267 V to 3.333 V)
- 1% maximum load regulation ensuring tight 3.3 V output accuracy under varying load conditions for sensitive digital logic
- Compact 7-pin SMA surface mount module integrating a complete DC-DC conversion stage for fast design-in without discrete magnetics
What is IZ0503SA used for?
The IZ0503SA is used in embedded systems, industrial I/O modules, and sensor interfaces that require a stable 3.3 V supply derived from a 5 V or 9 V bus. Its regulated single-output design and 1% load regulation make it suitable for powering microcontrollers, FPGAs, and communication transceivers in space-constrained equipment. The compact 7-pin SMA module eliminates the need for an external transformer and filter components, reducing BOM complexity.

Frequently Asked Questions
What input voltage range and output voltage does the IZ0503SA support?
The IZ0503SA accepts an input voltage from 4.5 V to 9 V and regulates a 3.3 V output (3.267 V to 3.333 V) with a maximum load regulation of 1%. This makes it compatible with standard 5 V logic supplies and 9 V battery packs common in industrial and embedded designs.
How does the IZ0503SA's 1% load regulation benefit digital logic designs?
A 1% load regulation means the IZ0503SA holds its 3.3 V output within ±33 mV from no load to full load. This tight window satisfies the ±5% tolerance band on 3.3 V rails specified for most CMOS microcontrollers, FPGAs, and DDR memory, preventing logic glitches or data corruption under dynamic current draw.
What PCB footprint does the IZ0503SA occupy and how does it simplify design?
The IZ0503SA is housed in a 7-pin SMA surface mount package, integrating the entire DC-DC conversion stage including transformer, switching controller, and output filter. This module approach eliminates at least 10 to 15 discrete components from the BOM, saving PCB area compared to a discrete design while meeting EN 55022 EMI standards for conducted emissions.
