XC6221B181MR-G

LDO Regulator Pos 1.8V 0.25A 5Pin 5SOT-25 T/R

■ GENERAL DESCRIPTION

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 CL will be discharged by the internal auto-discharge switch, and as a result the VOUT pin quickly returns to the VSS level. The output stabilization capacitor CL is also compatible with low ESR ceramic capacitors.
