DESCRIPTION

The A6110 is a low-dropout regulator that operates the input voltage from 2.5V to 6V and delivers 1 A load current. The A6110 is available in fixed output voltage. The output voltage of the fixed types is preset at an internally trimmed voltage 1V, 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 2.7V, 2.8V, 2.85V, 3.0V, 3.2V, 3.3V, 5V or can be made with options of the output range from 1V to 5V in 50mV increments.

The A6110 consists of a voltage reference unit, an error amplifier, resistor net for setting output voltage, a current limit circuit for over-current and a thermal-shutdown circuit.

The A6110 is available in TO252-3 and SOT223-3 packages.
