manufactured using CMOS and laser trimming technologies.
The series provides large currents with a significantly small
dropout voltage. The PJ2700 consists of a current limiter
circuit, a driver transistor, a precision reference voltage and an
error amplifier. Output voltage is selectable in 0.1V steps
between 2.0V ~ 6.0V in TO-92, SOT-89 and SOT-23 packages are
available.
