JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD 45V Low Current Consumption 250mA CMOS Voltage Regulator CJ86 XX Series  INTRODUCTION The CJ86XX series are a group of positive voltage regulators manufactured by CMOS technologies with low power consumption and low dropout voltage, which provide large output currents even when the difference of the input-output voltage is small. The CJ86XX series can deliver 250mA output current and allow an input voltage as high as 45V. The series are very suitable for the battery-powered equipments, such as RF applications and other systems requiring a quiet voltage source.  Wireless Communication Equipments  Portable Audio Video Equipments  Car Navigation Systems  FEATURES  Low Quiescent Current: 2μA    Operating Voltage Range: 2.5V～45V Output Current: 250mA Low Dropout Voltage： 700mV@100mA(VOUT=3.3V) Output Voltage: 2.1~ 12V High Accuracy: ±2%/±1%(Typ.)

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods my affect device reliability. (2) All voltages are with respect to network ground terminal. (3) This IC includes over temperature protection that is intended to protect the device during momentary overload. Junction temperature will exceed 125°C when over temperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability.  RECOMMENDED OPERATING CONDITIONS PARAMETER  MIN. NOM. MAX.
