L79L05ABUTR Description

Short technical summary and product information.

The ST L79L05ABUTR is a linear voltage regulator from the L79L series, designed to provide a stable negative voltage output. This component offers a fixed output voltage of -5V and can deliver an output current of up to 100mA, provided adequate heat-sinking is employed.

 

Key features include internal current limiting and thermal shutdown, making the device highly reliable and essentially indestructible under normal operating conditions. It requires no external components for its basic operation, simplifying circuit design and reducing component count. The regulator is available with voltage tolerances of ±5% or ±10%.

 

Intended for a wide range of applications, the L79L05ABUTR is suitable for local on-card regulation, helping to eliminate noise and distribution problems. It can also be used with power pass elements to create high-current voltage regulators. The TO-92 package is suitable for through-hole mounting.

 

This device serves as an effective replacement for Zener diode/resistor combinations, offering improved output impedance, lower quiescent current, and reduced noise.
