LM723CN Voltage Regulator IC
The LM723CN Voltage Regulator IC is a versatile and reliable component for designing high-performance regulated power supplies. It operates across a wide output voltage range of 2V to 37V, supporting both linear regulation and switching regulation modes.
Housed in a DIP-14 package, the LM723CN integrates voltage reference, error amplifier, and current limiting features, making it suitable for both low-current and high-current applications (with external pass elements). With thermal shutdown and short-circuit protection, it ensures safe and consistent operation.
Whether you’re building bench power supplies, battery chargers, or DC-DC converters, the LM723CN offers the precision and flexibility engineers demand.
