78L33A中文资料意法半导体数据手册PDF规格书

描述 Description

The L78L series of three-terminal positive regulators employ internal current limiting

and thermal shutdown, making them essentially indestructible. If adequate heat-sink

is provided, they can deliver up to 100 mA output current. 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. 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.
