XC6214 Series

High Speed LDO Regulators, Thermal Shutdown

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 0.1V increments within the range of 1.2V to 5.0V. (Output voltage 1.2V, 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.
