The XC6213 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The series achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor.
Output voltage is selectable in 0.05V increments within a range of 1.2V ~ 5.0V. The series is also compatible with low ESR ceramic capacitors, which give added output stability. The current limiter's foldback circuit also operates as a short protect for the output current limiter and the output pin.
The CE function enables the output to be turned off, resulting in greatly reduced quiescent current.
