LR1803

UNISONIC TECHNOLOGIES CO., LTD LR1803 Preliminary LINEAR INTEGRATED CIRCUIT 700mA HIGH SPEED LDO REGULATOR WITH REVERSE CURRENT PROTECTION  DESCRIPTION The UTC LR1803 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 LR1803 suitable for low voltage microprocessor application. The low quiescent current operation and low dropout quality caused by the CMOS process. The UTC LR1803 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 curre...
