■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.
Ultra small package, SSOT-24, SOT-25, and USP-4 are
available.
