| www..com PJ2700 Series Low Noise CMOS Positive Voltage Regulators T he PJ2700 series are highly precise, low noise, ultra low power consumption, positive voltage regulators TO-92 Pin 1.Gnd 2. In 3. Out 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. SOT-89 FEATURES Maximum Output Current:300mA Dropout Voltage :300mV @ 100mA Maximum Operating Voltage : 10V Output Voltage Range :2.0V~6.0V(selectable in 0.1V steps) Highly Accurate : 2% Low Power Consumption : TYP 2A at Vout=5.0V Operational Temperature Range : -20 ~ 85 Ultra Small Packages : TO-92, SOT-89, SOT-23 Applications Mobile phones Cordless phones Cameras, video recorders Portable games Portable AV equipment CD-Rom, DVD and LAN Card Battery powered equipment Device PJ27xxCT PJ27xxCY PJ27xxCX SOT-23 Pin 1.
