L4940XX中文资料意法半导体数据手册PDF规格书

描述 Description

The L4940 series of three terminal positive regulators is available in TO-220, TO-220FP and D2PAK packages and with several fixed output voltages, making it useful in a wide range of industrial and consumer applications. Thanks to its very low input/output voltage drop, these devices are particularly suitable for batteries powered equipment, reducing consumption and prolonging battery life. Each type employs internal current limiting, antisaturation circuit, thermal shut-down and safe area protection.
