 DESCRIPTION
As a low dropout linear regulator, the UTC L1127/A/E only needs
low input voltage (2.5~6V), and can deliver current to 300mA for
setting the output voltage.
The UTC L1127/A/E is ideal for being used in such as
battery-powered equipments notebook, personal computer and
mother board. Its typical dropout voltage is 230mV at loading current
300mA.
L1127/A/E has 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.3V, 4.2V,
4.75V, fixed voltage versions and 0.8V to 5.5V adjustable voltage
versions.
ERROR Flag (L1127E): ERROR Flag goes low when the
output voltage drops 10% below nominal value .
ADJ/SET (L1127A): Connect ADJ/SET to GND for Preset output;
Connect an external resistive voltage-divider from OUT to GND to set
the out voltage between 0.8V and 5.5V.
