XC6220B331MR

The XC6220xx series are high-precision, low-noise, fast-response LDO linear regulators fabricated using CMOS process technology. These regulators integrate a fixed reference voltage, error correction circuit, current limiting circuit, phase compensation circuit, and a low on-resistance MOSFET, achieving high ripple rejection, low output noise, and fast-response low-dropout performance. The series is compatible with ceramic capacitors, which are smaller in size than tantalum capacitors, and eliminates the need for a 0.1μF bypass capacitor, saving board space and reducing cost. With high-precision output regulation and fast transient response, the series handles load current fluctuations effectively, making it particularly suitable for handheld devices and RF products. The output can be disabled via the CE pin on the chip; the typical quiescent current in shutdown mode is only 0.1μA, significantly reducing power consumption.
