UNISONIC TECHNOLOGIES CO., LTD LR1802 Preliminary 1.0A LOW DROPOUT LINEAR REGULATOR WITH OUTPUT VOLTAGE SETTING OPTIONS CMOS IC  DESCRIPTION The UTC LR1802 is a typical LDO that features output voltage setting options, very low dropout voltage as low as 0.3V at output current 1.0A, an enable input and the soft-start reduces inrush current of the load capacitors and minimizes stress on the input power source during start-up. An enable pin to further reduce power dissipation while shutdown.. The UTC LR1802 is stable with any type of output capacitor of 10µF or more. A precision reference and feedback control deliver 3% accuracy. HSOP-8  FEATURES * Low VIN and wide VIN range: 1.0V~5.5V * Bias voltage (VPP) range: 3.0V~5.5V * Low VOUT range: 0.8V~3.3V * 300mV dropout @1.
