Overview
The L78L06ACUTR is a part of the L78L series of three-terminal positive voltage regulators produced by STMicroelectronics. These regulators are designed to be highly robust, featuring internal current limiting and thermal shutdown, making them essentially indestructible. With adequate heat-sinking, they can deliver up to 100 mA of output current. The L78L series is intended for use in a wide range of applications, including local or on-card regulation to eliminate noise and distribution problems associated with single-point regulation. They can also be used with power pass elements to create high-current voltage regulators and as a replacement for Zener diode/resistor combinations, offering improvements in quiescent current and noise reduction.
