# Supply Current vs. Input Voltage

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.
