CJ6212 Series
The CJ6212 series are a group of positive
voltage regulators manufactured by CMOS
technologies with high ripple rejection, ultra
low noise, low power consumption and low
dropout voltage, which can prolong battery
life in portable electronics.
The CJ6212 series work with low-ESR ceramic
capacitors, reducing the amount of board
space necessary for power applications. The
CJ6212 series consume less than 0.1μA in
shutdown mode and have fast turn-on time
less than 50μs.The series are very suitable for
the battery-powered equipments, such as RF
applicationsand other systems requiring a quiet
voltage source.
Hot swap without overshoot
