700mA HIGH SPEED LDO  REGULATOR WITH REVERSE  CURRENT PROTECTION  

 

 

 

DESCRIPTION

 

The UTC UR6227 operate from a +1.7V ~ +6V input supply as

fast low-dropout linear regulators. Wide output voltage range

options are available. The fast  response characteristic to make

UTC UR6227 suitable for low voltage microprocessor application.

The low quiescent current operation and low dropout quality

caused by the CMOS process.  

The UTC UR6227 has low dropout voltage. The ground pin

current is typically 100μA. Output Voltage Precision: Multiple

output voltage options are available and ranging from 1.5V~5V at

room temperature with a guaranteed accuracy of ±1.5%, and

±3.0% when varying line and load.  With the reverse current

protection unction 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 UR6227.
