GENERAL DESCRIPTION
The XC6209 series are 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.
