LP3928 High Speed Bi-Directional Level Shifter and Ultra Low-Dropout CMOS Voltage
Regulator
General Description
The LP3928 is designed for portable and wireless applications with demanding performance and space requirements.
The LP3928 provides level shifting and power conversion needed for applications interfacing differing voltage levels.
The part contains a bi-directional level shifter for three signals to translate the levels between 1.
8V and 2.
85V and an ultra low-dropout CMOS 2.
85V voltage
regulator.
The three level shifted signals are individually direction controlled.
