LP3928 High Speed Bi-Directional Level Shifter and Ultra Low-Dropout CMOS Voltage Regulator
October 2002
LP3928
High Speed Bi-Directional Level Shifter and Ultra
Low-Dropout CMOS Voltage Regulator
General Description
The LP3928 is designed for portable and wireless applica-
tions 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 sig-
nals 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 con-
trolled. Signals going from 2.85V to 1.8V can also be latched
using an external clock source. The latches are powered
from internal 2.85V. There is also an option to by-pass the
latches.
The built-in low-dropout voltage regulator is ideal for mobile
phone and battery powered wireless applications. It provides
up to 150 mA from a 3.05V to 6.0V input, and is character-
ized by extremely low dropout voltage, low quiescent current
and low output noise voltage. It is stable with small 1.5 碌F
鹵
30% ceramic and high quality tantalum output capacitors,
requiring smallest possible PC board area.
A shutdown mode is available for the level shifters and the
regulator. High performance is achieved over various load
conditions with very low rise and fall times.
