SIM Card Level Shifter with 50mA LDO

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. This simplifies the design of the SIM card interface.
