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 b...
