■GENERAL DESCRIPTION
The XC6210 series are precise, low noise, high current, positive
voltage low dropout regulators. They are fabricated using
Torex’s CMOS process.
The series features a voltage reference, an error amplifier, a current
limiter, and a phase compensation circuit plus a driver transistor.
With a low ON resistance driver transistor built into, batteries
can be used until input-output voltage differential is minimal and
can accordingly be used for a longer time.
The series is also compatible with low ESR ceramic capacitors
which give added output stability.
The output voltage of the LDO is selectable in 50mV increments
within the range of 0.8V to 5.0V.
The current limiter's foldback circuit also operates as the output
current limiter and the output pin protection.
The IC's internal regulator circuit can be placed in stand-by
mode via the CE function. In the stand-by mode, power
consumption is greatly reduced.
