! GENERAL DESCRIPTION
The XC6212 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 0.9V ~
6.0V.
The series is also compatible with low ESR ceramic capacitors which
give added output stability. This stability can be maintained even during
load fluctuations due to the excellent transient response of the series.
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.
