TDSEMIC XC6220B181MR

The XC6220xx 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 than tantalum capacitors and requires no 0.1μF bypass capacitor, further saving board space and reducing cost. With high-accuracy output stability and fast transient response, the series effectively handles load current fluctuations, 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.
