XC6221

Series

■GENERAL

DESCRIPTION

ETR0328_015

The XC6221 series is a high accuracy, low noise, high speed, low dropout CMOS regulator with high ripple rejection. The series

includes a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit.

The CE function enables the entire circuit to be in stand-by state by inputting low level signal. As for the XC6221B/D stand-by

mode, the electric charge at the output capacitor (C

) will be discharged by the internal auto-discharge switch, and as a result

the V

OUT

pin quickly returns to the V

level. The output stabilization capacitor (C

) is also compatible with low ESR ceramic

capacitors.

Output voltage is selectable in 0.05V increments within a range of 0.80V~5.00V, using the laser trimming technology set in

factory.

The current limiter's fold-back circuit also operates as a short circuit protection and an output current limiter at the output pin.

The series achieves a fast response with only 25μA of low power consumption. Also the series has low dropout voltage

characteristics, which is 80mV at I

OUT

=100mA and V

OUT

=3.0V.

With the use of small USP-4 and ultra small USPN-4 packages, a small footprint circuit can be designed.
