L4940P85

非常低压降1.5 A稳压器 Very low drop 1.5 A regulator

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.
