XC6221
Series
■GENERAL
DESCRIPTION
ETR0328_011a
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
L
) will be discharged by the internal auto-discharge switch, and as a result
the V
OUT
pin quickly returns to the V
SS
level. The output stabilization capacitor (C
L
) 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.
