UNISONIC TECHNOLOGIES CO., LTD LR1108/E CMOS IC 1A FAST ULTRA LOW DROPOUT LINEAR REGULATOR 1 SOT-223 1 TO-252  DESCRIPTION The UTC LR1108/E is an ultra low-dropout linear regulators. Wide output voltage range options are available. The fast response characteristic to make UTC LR1108/E suitable for low voltage microprocessor application. The low quiescent current operation and low dropout quality caused by the CMOS process. The UTC LR1108/E has ultra low dropout voltage 300mV at 1A load current typically. The ground pin current is typically 150uA at 1mA load current. ERROR Flag: When the output voltage drops 10% below nominal value Error flag goes low. SET/ADJ Mode (for LR1108): Connect an external resistive voltage-divider from VOUT to this pin to set the output voltage from 1.
