XC6221B302MR.

The XC6221B302MR is a 3V fixed output low-noise high-speed low-dropout (LDO) CMOS Linear Regulator with high ripple rejection. The device 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 device 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. The current limiters fold-back circuit also operates as a short circuit protection and an output current limiter at the output pin.

• ±1% Output accuracy
• 25μA Low power consumption (typical)
• Less than 0.1μA stand-by current
• 70dB at 1kHz High ripple rejection
• 1µF Low ESR ceramic capacitor
