The XC6203E 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 XC6203E consists of a driver transistor, a precision reference
voltage and an error amplifier. Output voltage is selectable in 0.1V steps
between a voltage of 1.8V and 6.0V.
SOT-89 (500mW), SOT-223 (1200mW) and TO-92 (300mW) package.
