LR1812 Datasheet
 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.

 

FEATURES

 

* Low Dropout Voltage

* The Guaranteed Output Current is 1A DC

* Output Voltage Accuracy ± 1.5%

* Over temperature Protection And Over current Protection

* Reverse Current Protection
