A6110
LOW DROPOUT VOLTAGE REGULATOR
1A CMOS, LOW CONSUMPTION
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 two types, either
fixed or adjustable 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 output range of adjustable types is
from 1V to 5V. The adjustable output voltage is only
available in SOT-89-5 package.
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.
A standby mode with ultra low supply current can be
realized with the chip enable function.
The A6110 is available in DFN-6, SOT-89-5,
SOT-89-3, SOT-223-5, SOT-223-3, TO-263-3,
TO-220-3, TO-252-3 and TO-252-5 packages.
