■GENERAL DESCRIPTION
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 50mV 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 power consumption.
