STMicroelectronics 78L33
The L78L series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. They are intended as fixed voltage regulators in a wide range of applications including local or oncard regulation for elimination of noise and distribution problems associated with single-point regulation.| Part No. | 78L33 |

DESCRIPTION
If adequate heat-sink is provided, they can deliver up to 100 mA output current. In addition, they can be used with power pass elements to make high-current voltage regulators. The L78L series used as Zener diode/resistor combination replacement, offers e improvement along with lower quiescent current and lower noise.
