L7905CV Description

Short technical summary and product information.

The STMicroelectronics L7905CV is a three-terminal negative voltage regulator in the L79xxC series, designed for a wide range of applications. This device offers a fixed output voltage of -5V and can deliver an output current of up to 1.5A when adequate heat sinking is provided.

 

Key features include thermal overload protection, short circuit protection, and output transition SOA protection, ensuring reliable operation. The regulator is available in a TO-220 package, suitable for through-hole mounting.

 

These regulators are useful for local on-card regulation, helping to eliminate distribution problems associated with single-point regulation. They are particularly suited for split power supplies when used with the L78xx positive standard series. The device operates within a temperature range of 0°C to 125°C.

 

While primarily designed as fixed voltage regulators, the L7905CV can be used with external components to achieve adjustable voltages and currents. Its robust design and protective features make it a versatile component for various power management circuits.
