Low Output Noise (27uVRMS
)
The LR6155 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 1.3V to 5.0V. Typical output noise is
27uVRMS, and PSRR is 65dB at 1KHz.
Standby Mode: 0.1uA
150mA output current for each channel
25uA Operating Supply Current per channel
High Ripple Rejection: 65dB@1KHz(Typ.)
Low 130mV dropout at 100mA load
Excellent Line Regulation: 0.05%/V
Built-in chip Enable Circuit
The LR6155 includes two independent
logic-controlled shutdown inputs and allows the
output of each regulator to be turned of
independently.
Independent Shutdown Controls
Output Voltage Range: 1.3V~5.0V
250mA Output Current Limit
Highly Accurate: 2% ( ±1% customized)
±
The LR6155 includes high accuracy voltage
reference, error amplifier, current limit circuit and
output driver module.
TSOP-6 Package
W
e declare that the material of product
compliance with RoHS requirements.
The LR6155 has excellent load and line transient
response and good temperature characteristics,
which can assure the stability of chip and power
system and LR6155 uses trimming technique to
guarantee output voltage accuracy within ±2%.
