.. LP3929 High Speed Bi-Directional Level Shifter and Ultra Low-Dropout CMOS Voltage Regulator and Line Protection July 2006 LP3929 High Speed Bi-Directional Level Shifter and Ultra Low-Dropout CMOS Voltage Regulator and Line Protection General Description The LP3929 is designed for portable and wireless applications requiring level translation and power supply generation in a pact footprint. The device level translates 1.8 V LVCMOS on the host (A) side to 2.85 V LVCMOS levels on the card (B) side for a miniSD / SD 4-bit bi-directional data bus. Independent direct control of the CMD, Data0 and Data1-3 paths support mini SD state machine requirements. A shutdown pin...
