________________________________________________________________________________________________________________ ● XC6203 Series (Large Current) Positive Voltage Regulators DETAILS General Description Features Maximum Output Current: 400mA Maximum Operating Voltage: 10V Output Voltage Range: 2.0V to 6.0V (selectable in 0.1V steps) Highly Accurate: ± 2% Low Power Consumption: TYP 8.0 µA Output Voltage Temp. Characteristics: TYP 100ppm/°C Operational Temperature Range: -40°C to 85°C Ultra Small Package: SOT-89 The XC6203 series are highly precise, low power consumption, positive voltage regulators manufactured using CMOS and laser trimming technologies. The series provides large currents with a significantly small dropout voltage. The XC6203P consists of a current limiter circuit, a driver tran sistor, a precision reference voltage and an error amplifier. Output voltage is selectable in 0.1V steps between a voltage of 2.0V and 6.0V. The IC benefits from output current control & output pin short protection as a result of the built-in current limiter (foldback) circuit. SOT-89 (500mW) package.
