DESCRIPTION

The A6110C series are highly accurate, low noise, low dropout and very fast turn-on times CMOS LDO Voltage Regulators. The A6110C includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The A6110C’s current limiters' foldback circuit also operates as a short protect for the output current limiter and. the output pin. The A6110C series is 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 EN function allows the output of regulator to be turned off, resulting in greatly reduced power consumption.

The A6110C is available in SOT-25 and SOT89-5 packages.
