Product Introduction

Overview

The L78L10ACUTR is a member of the L78L series of three-terminal positive voltage regulators produced by STMicroelectronics. These regulators are designed to provide stable output voltages with internal current limiting and thermal shutdown, making them highly reliable and 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 in conjunction with power pass elements to create high-current voltage regulators and serve as a replacement for Zener diode/resistor combinations, offering lower quiescent current and noise.
