The UTC
LR1108/E/N
is an ultra low-dropout linear
regulators. Wide output voltage range options are available. The
fast response characteristic to make UTC
LR1108/E/N
suitable
for low voltage microprocessor application. The low quiescent
current operation and low dropout quality caused by the CMOS
process.
The UTC
LR1108/E/N
has ultra low dropout voltage
300mV at 1A load current typically.
The ground pin current is typically 150uA at 1mA load current.
ERROR Flag: When the output voltage drops 10% below
nominal value Error flag goes low.
SET/ADJ Mode (for
LR1108):
Connect an external resistive
voltage-divider from V
OUT
to this pin to set the output voltage from
1.145V to 5V.
Output Voltage Precision: Multiple output voltage options are
available and ranging from 1.2V ~ 5.0V at room temperature with
a guaranteed accuracy of ±1.5%, and ±3.0% when varying line,
load and temperature.
