Preliminary
3A LOW DROPOUT LINEAR
REGULATOR
CMOS IC
„ DESCRIPTION
The UTC LR8845 belonged to low quiescent current, low
dropout linear regulators operated from 2.5V to 6V input and are
guaranteed to deliver 3A. Wide range of preset output voltage
options are available. Built-in low on-resistance transistor provides
low dropout voltage and large output current. The UTC LR8845 is
designed and optimized for battery-powered systems to work with
low noise.
The UTC LR8845 consumes less than 2μA in shutdown mode.
Other features include ultra low dropout voltage, current limiting
protection, thermal shutdown protection and high ripple rejection
ratio.
