L78L05ACD Description

Short technical summary and product information.

The STMicroelectronics L78L05ACD is a three-terminal positive voltage regulator designed for a wide range of applications. It offers a fixed output voltage of 5V and can deliver an output current of up to 100 mA. The device incorporates internal current limiting and thermal shutdown, making it highly reliable and resistant to damage.

 

Key electrical characteristics include an input voltage range up to 30V and a typical quiescent current of 5.5mA. It also features a Power Supply Ripple Rejection (PSRR) of 49dB at 120Hz. The operating temperature range is from 0°C to 125°C.

 

This regulator is available in an 8-SOIC package, suitable for surface mounting. Its design eliminates the need for external components, simplifying circuit design and reducing board space. The L78L05ACD is intended for local or on-card regulation, helping to eliminate noise and distribution problems associated with single-point regulation.
