Description

The SN79Lxxx series are three-terminal Negative regulators providing

over 100mA output current with internal current limiting, thermal

shutdown and safe area protection. These regulators are useful in

a wide range of applications. Although they are just fixed voltage

regulators, the SN79Lxxx series can be used with external components to

obtain adjustable voltages and Currents. It also contains the TCE Cell to

protect internal circuit from ESD damage.
