Description

The XC6213B122NR is a highly accurate, low noise, CMOS LDO Voltage Regulator in the XC6219/XC6211 series. It offers low output noise, high ripple rejection ratio, low dropout, and very fast turn-on times. The XC6219/6211 series is ideal for cutting-edge mobile phones. Internally, it includes a reference voltage source, error amplifiers, driver transistors, current limiters, and phase compensators. The current limiters foldback circuit also operates as a short protect for the output current limiter and the output pin. The output voltage can be set by laser trimming in steps of 50mV within a range of 0.9V to 5.0V. The XC6219/6211 series is fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. Its high level of output stability is maintained even during frequent load fluctuations, thanks to excellent transient response performance and high PSRR across a broad range of frequencies. The CE function allows the output of the regulator to be turned off, resulting in greatly reduced power consumption.
