L79L05ABD Description

Short technical summary and product information.

The STMicroelectronics L79L05ABD is a three-terminal negative 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, provided adequate heat sinking is supplied.

 

Key electrical specifications include an input voltage range of up to -30V and protection features such as thermal overload and short circuit protection, making the device essentially indestructible. The regulator operates over a wide temperature range from -40°C to 125°C.

 

This device is suitable for local or on-card regulation, helping to eliminate noise and distribution problems associated with single-point regulation. It is available in an 8-SOIC surface mount package, requiring no external components for basic operation.

 

The L79L05ABD series can also be used with power pass elements to create high-current voltage regulators and offers improved output impedance compared to traditional Zener diode/resistor combinations.
