XC6219B182MR

The XC6219xx series are high-accuracy, low-noise, fast-response LDO linear regulators fabricated using a CMOS process. 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 — smaller in size than tantalum capacitors — and eliminates the need for a 0.1μF bypass capacitor, helping to save board space and reduce cost. With high-accuracy output stability and fast transient response, the series effectively handles load current fluctuations, making it particularly well-suited for handheld devices and RF products. 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.
