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.

Note: 1. VOUT (T)=Specified Output Voltage. 2. VOUT (E)=Effective output Voltage (i.e. the output voltage when "VOUT(T)+1.0" is provided while maintaining a certain IOUT value). 3. Vdif={VIN1(Note5)- VOUT1(Note4)} 4. VOUT 1=A voltage equal to 98% of the output voltage when a stabilized (VOUT(T)+1.0V) is input. 5. VIN=The input voltage at the time VOUT 1 is output (input voltage has been gradually reduced).
