600mA High PSRR Low Noise LDO
EM1106
General Description
The EM1106 performs ultra low drop voltage,
high power supply rejection ratio (PSRR), fast
response, low noise linear regulator, and designed
to continuously deliver up to 600mA output current.
The EM1106 has wide adjustable output voltage
range and high output accuracy to 2%.
No by-pass capacitor is needed for this device
and only 1uF ceramic capacitor is required for
stability in any loading conditions. It reduces the
amount of board space necessary for power
applications.
The other features include soft start, current
limit protection, Power-On-Reset function, and
over temperature protection. The EM1106 is
available in SOT-23-5 package.

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the
device. These are for stress ratings. Functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may remain possibility to
affect device reliability.
Note 2. θJA is measured in the natural convection at TA=25oC on a low effective thermal conductivity test
board of JEDEC 51-3 thermal measurement standard.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
