L78L09ACZ Description

Short technical summary and product information.

The STMicroelectronics L78L09ACZ is a three-terminal positive voltage regulator designed for a wide range of applications. It offers a fixed 9V output voltage and can deliver an output current of up to 100 mA. This device incorporates internal current limiting and thermal shutdown, making it highly reliable and essentially indestructible under normal operating conditions.

 

Key electrical features include a typical quiescent current of 5.5 mA and a PSRR of 44dB at 120Hz. The input voltage range extends up to 30V, and it operates within a temperature range of 0°C to 125°C. Protection features include over current, over temperature, and short circuit protection.

 

The L78L09ACZ is supplied in a TO-92-3 package, suitable for through-hole mounting. It is intended for local or on-card regulation, helping to eliminate noise and distribution problems associated with single-point regulation. It can also be used with power pass elements to create high-current voltage regulators.
