GENERAL DESCRIPTION
The XC6214 series are highly 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, a thermal
protection circuit, and a phase compensation circuit plus a
driver transistor.
The output voltage is selectable in 100mV increments within the
range of 1.5V to 5.0V
.
(Output voltage 1.5V, 1.8V, 2.5V, 3.0V
and 3.3V are standard products. Other than these voltages
are available as semi-custom products.)
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 over current protection circuit and the thermal shutdown
circuit are built in. The over current protection circuit will
operate when the output current reaches current limit level.
The thermal shutdown circuit will operate when the junction
temperature reaches temperature limit level.
