LR3965
1.5A LOW DROPOUT LINEAR
REGULATOR
DESCRIPTION
The UTC
LR3965
belonged to low-noise, low-dropout, linear
regulators operate from 2.25V to 6V input and are guaranteed to
deliver 1.5A.
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
LR3965
is designed and
optimized for battery-powered systems to work with low noise.
The UTC
LR3965
consumes less than 0.01μA in shutdown
mode.
Other
features include ultra low dropout voltage, current
limiting protection, thermal shutdown protection and high ripple
rejection ratio.
