A6155
LOW DROPOUT VOLTAGE REGULATOR
150mA DUAL OUTPUT CMOS LOW NOISE
DESCRIPTION
The A6155 is a dual output, low noise; low-dropout
regulator delivers at least 150mA of continuous
output current. The output voltage for each
regulator is set independently by trimming.
Voltages are selectable in 100mV steps within a
range of 1.2V to 5.0V. Typical output noise is
27uVRMS, and PSRR is 65dB at 1KHz.
The A6155 includes two independent
logic-controlled shutdown inputs and allows the
output of each regulator to be turned of
independently.
The A6155 includes high accuracy voltage
reference, error amplifier, and current limit circuit
and output driver module.
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.
