PJ2700 Series
Low Noise CMOS Positive Voltage Regulators
1-5 2002/10.rev.A
he PJ2700 series are highly precise, low noise, ultra 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 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.
