L78L33ACD Description

Short technical summary and product information.

The STMicroelectronics L78L33ACD is a versatile linear voltage regulator designed for a wide range of applications. It provides a stable 3.3V output voltage with a maximum output current of 100mA. This device features internal current limiting and thermal shutdown, making it highly reliable and protected against over-current and over-temperature conditions.

 

The L78L33ACD is suitable 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 for higher current applications. The regulator operates over a temperature range of 0°C to 125°C and requires no external components for basic operation.

 

This component is supplied in an 8-SOIC package, designed for surface mounting. Its fixed output voltage and robust protection features make it a practical choice for various electronic designs requiring a reliable 3.3V power supply.
