DESCRIPTION

The A6700 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The A6700 series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error correction, current limiter and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 100mV increments within a range of 1.0V ~ 5.0V.

The A6700 series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the A6700 series.

The CE function enables the output to be turned off,

Resulting in greatly reduced power consumption.

The A6700 is available in SOT-25 and SOT89-5 packages.
