LOW DROPOUT VOLTAGE REGULATOR
150mA DUAL OUTPUT CMOS LOW NOISE
DESCRIPTION
FEATURES
The A6155 is a dual output, low noise; low-dropout
Low Output Noise (27uVRMS)
regulator delivers at least 150mA of continuous
Standby Mode: 0.1uA
output current.
150mA output current for each channel
The output voltage for each
regulator is set independently by trimming.
25uA Operating Supply Current per channel
Voltages are selectable in 100mV steps within a
High Ripple Rejection: [email protected](Typ.)
range of 1.2V to 5.0V.
Low 200mV dropout at 100mA load
27uVRMS, and PSRR is 65dB at 1KHz.
Excellent Line Regulation: 0.05%/V
Built-in chip Enable Circuit
The A6155 includes two independent
Independent Shutdown Controls
logic-controlled shutdown inputs and allows the
Output Voltage Range: 1.2V~5.0V
output of each regulator to be turned of
Output Current Limit
Typical output noise is
independently.
Highly Accurate: ±2% (±1% customized)
The A6155 includes high accuracy voltage
Available in SOT-26 Package
reference, error amplifier, and current limit circuit
and output driver module.
APPLICATION
The A6155 has excellent load and line transient
response and good temperature characteristics,
which can assure the stability of chip and power
system and A6155 uses trimming technique to
guarantee output voltage accuracy within ±2%.
The A6155 is available in SOT-26 package.
