UNISONIC TECHNOLOGIES CO., LTD UR6225 CMOS IC POSITIVE VOLTAGE REGULATOR DESCRIPTION The UTC UR6225 is a positive voltage output, three-pin regulator that provides a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and laser trimming technologies. The UTC UR6225 consists of a high-precision voltage reference, an error amplification circuit, and a current limited output driver. Transient responses to load variations have improved in comparison to the existing series. FEATURES * Maximum Output Current: 300mA (Within Max. Power Dissipation, VOUT = 5.0V) * Output Voltage Range: 1.2V ~ 6.0V in 0.1V Increments (1.2V ~ 1.9V for Custom Products) * Highly Accurate: Output
