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 (C
L
) to be discharged via the internal auto-discharge resistance, and as a
result the V
OUT
pin quickly returns to the V
SS
level. The series' output stabilization capacitor (C
L
) 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 25
A of low power consumption. Also the series has low dropout
voltage characteristics, which is 80mA at I
OUT
=100mA and V
OUT(T)
=3.0V.
With the use of ultra small package, USP-4 package, a small footprint circuit can be designed.
