LR1812
1.0A FAST ULTRA LOW
DROPOUT LINEAR
REGULATOR WITH REVERSE
CURRENT PROTECTION
 DESCRIPTION
The UTC LR1812 operate from a +1.5V ~ +6V input supply as
fast ultra low-dropout linear regulators. Wide output voltage range
options are available. The fast response characteristic to make
UTC LR1812 suitable for low voltage microprocessor application.
The low quiescent current operation and low dropout quality
caused by the CMOS process.
The UTC LR1812 has low dropout voltage. The ground pin
current is typically 60uA.
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 and
load.
With the reverse current protection function of a driver
transistor, the reverse current flow is prohibited when VOUT
voltage is higher than VIN voltage. For an example, when a battery
is connected to the VOUT pin, battery current will not flow back to
the UTC LR1812
The output voltage types of UTC LR1812-xx are fixed one in
the IC.
