XC6219 Series

300mA High Speed LDO Regulator with ON/OFF Control

The XC6219 series are highly accurate, low noise, CMOS LDO voltage regulators. Offering low output noise, high ripple rejection ratio, low dropout and very fast turn-on times, error amplifiers, driver transistors, current limiters and phase compensation circuit internally.

The XC6219's current limiters' foldback circuit also operates as a short protect for the output current limiter and the output pin.

The output voltage is set by laser trimming. Voltages are selectable in 0.05V steps within a range of 0.9V to 5.0V. The XC6219 series are also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies.

The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption.

FAQ

QuestionWhat is the standby current?
Answer

The current that flows through the IC in the standby mode. The standby mode means the state where the IC has been turned off by the CE function.
