The Murata Power Solutions 7803SRH-C is a step-down switching regulator designed for efficient voltage regulation in a compact TO-220-3 package. It offers output options of 3.3V at 0.5A, 5V at 0.5A, or 12V at 0.4A, with an input voltage range of 7.5V to 36V DC. The device achieves up to 95% efficiency, eliminating the need for heat sinks or thermal derating, and operates within a temperature range of -40¬8C to +70¬8C at full load. This regulator features built-in filter capacitors, requiring no external components, and provides excellent load and line regulation with tolerances of ¬±0.2% and ¬±0.3%, respectively. It is suitable for applications requiring reliable power from unregulated DC supplies and is compatible with existing LM7805 and LM7812 linear regulator footprints. The 7803SRH-C also includes short-circuit protection, making it a robust choice for various instrumentation and power supply applications.
