XC6214 Series
500mA Output Current, High Speed LDO Regulators, Thermal Shutdown Function, Ceramic Capacitor Compatible
ETR0318_009
GENERAL DESCRIPTION
The XC6214 series are highly precise, low noise, high current, positive voltage, low dropout voltage regulators. They are fabricated using 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 1.2V, 1.5V, 1.8V, 2.5V, 3.0V and 3.3V. The series is also compatible with low ESR ceramic capacitors, which provides stable output voltage. This stability can be maintained even during load fluctuations due to the excellent transient response. 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 limit current. The thermal shutdown circuit will operate when the junction temperature reaches limit temperature.
APPLICATIONS
DVD, CD-ROM, HDD drive equipment Portable audio visual equipment (Digital Still Cameras, Video Cameras) Wireless Communication equipment (Mobile Phones, Cordless phones) Desktop computers, Note book computer, PDAs Network equipment (Wireless LAN) Reference voltage Battery powered equipment
