LX8940 - 5V LOW DROPOUT REGULATOR

Description

The LX8940 is a 5V, low dropout, low quiescent current regulator rated for 1A of output current.

It can regulate with as low as 0.4V headroom between the input and output voltages, thus minimizing power dissipation.

Features

  • fault protection against overvoltage as well as a thermal shutdown feature. If the input voltage rises above 33V (load dump), the output shuts down automatically. The internal circuitry is thus protected and the IC is able to survive higher voltage transients than might otherwise be expected. The thermal shutdown output effectively guards against overheating of the die and protects the device from being damaged.

It can regulate with as low as 0.4V headroom between the input and output voltages, thus minimizing power dissipation. In addition, it can be used in applications where worst case supplies require a low input-output differential to maintain regulation. This feature makes it ideal for computer monitors that have to comply with energy-efficient / "Green PC" programs, where the input voltage drops to only a few tenths of a volt above the output when power supply enters sleep-mode operation.
