DESCRIPTION
FEATURES
The A6305 is a dual, low-noise, low-dropout
regulator delivering at least 300mA of continuous
output current. The output voltage for each regulator
is set independently by trimming.
Two Low Dropout Voltage Regulators
300mA Output Current for Each LDO
20uA Operating Supply Current Per LDO
Low 47μVRMS Output Noise
Voltages are selectable in 100mV steps within a
range of 1.5V to 4.5V. Typical output noise is
47μVRMS, and PSRR is 73dB at 100Hz.
Standby Mode:0.1μA
Low 160mV Dropout at 300mA load
73dB PSRR at 100Hz

Excellent Line regulation: 0.05%/V
Independent Shutdown Controls
1.5V to 4.5V Factory-Preset Output
Output Current Limit
logic-controlled shutdown inputs and allows the
output of each regulator to be turned of
independently.
The A6305 includes high accuracy voltage
reference, error amplifier, current limit circuit and
output driver module.
High Accuracy: ±2% (±1% customized)
Available in SOT-26 Package
The A6305 has excellent load and line transient
response and good temperature characteristics,
which can assure the stability of chip and power
system. And it uses trimming technique to
guarantee output voltage accuracy within ±2%.
