L78MXXAC中文资料意法半导体数据手册PDF规格书

描述 Description

The L78MxxAB series of three-terminal positive regulators is available in TO-220 and DPAK

packages and with several fixed output voltages, making it useful in a wide range of applications.

These regulators can provide local on-card regulation eliminating the distribution problems

associated with single point regulation. Each type employs internal current limiting, thermal shut

down and safe area protection, making it essentially indestructible. If adequate heat sinking

is provided, they can deliver over 0.5 A output current. Although designed primarily as fixed

voltage regulators, these devices can be usedwith external components to obtain adjustable

voltage and currents.
