... General Description The MIC4555 is a digital level shifter with a 50mA LDO for SIM Card interfaces. There are three high speed level shifters for SIM Card signal translation. The level shifters are designed to support high speed clocking up to 5MHz. The 50mA LDO provides power for the SIM Card to eliminate the need for a separate power device ...
