CMOS Low Power Supply Voltage Regulators Output Current: 200mA Dropout Voltage: 80mV@IOUT=100mA, VOUT(T)=3.0V Output Voltage Range: 0.8V ~ 4.0V Low ESR Capacitor Compatible High Ripple Rejection, Low Output Noise CL High-Speed Auto-Discharge (XC6221B) Ultra Small Package: USP-4 APPLICATIONS Cellular phones Cordless phones Wireless communication equipment Portable games Cameras, VCRs Portable AV equipment PDAs GENERAL DESCRIPTION The XC6221 series are precise, low noise, high speed, low dropout regulators. They are fabricated using Torex's CMOS process. Performance features of the series include high ripple rejection and low dropout voltage, and the series include a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit. The CE function enables the circuit to be in stand-by mode by inputing L level signal. In the stand-by mode, the series enables the electric charge at the output capacitor (CL) to be discharged via the internal auto-discharge resistance, and as a result the VOUT pin quickly returns to the VSS level. The series' output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. Output voltage is selectable in 50mV increments within a range of 0.8V~4.0V, using laser trimming technologies. The current limiter's foldback circuit also operates as a short circuit protection for the output current limiter and the output pin. The series achieves a great response with only 25A of low power consumption. Also the series has low dropout voltage characteristics, which is 80mA at IOUT=100mA and VOUT(T)=3.0V. With the use of ultra small package, USP-4 package, a small footprint circuit can be designed.
