LX8940
LX8940 is 5V LOW DROPOUT REGULATOR manufactured by Microsemi.
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. 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 puter monitors that have to ply 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.
