General Description
The GS7107 is a CMOS linear regulator. It is
featuring ultra-high power supply rejection ratio,
low output voltage noise, low dropout voltage, low
quiescent current and fast transient response. It
guarantees delivery of 200mA output current, and
supports preset 1.2V, 1.3V, 1.5V, 1.7V, 1.8V,
1.85V, 1.9V, 2.0V, 2.3V, 2.5V, 2.6V, 2.7V, 2.8V,
2.85V, 2.9V, 3.0V, 3.1V, 3.3V output voltage
versions.
Based on its low quiescent current consumption
and its less than 1uA shutdown mode, the
GS7107 is ideal for battery- powered applications.
The high power supply rejection ratio of the
GS7107 holds well for low input voltages typically
encountered in battery- operated systems. The
regulator is stable with small ceramic capacitive
loads (1µF typical).

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. Devices are ESD sensitive. Handling precaution recommended.
Note 3. θJA is measured in the natural convection at TA=25°C on a high effective thermal conductivity test
board (4 Layers, 2S2P) of JEDEC 51-7 thermal measurement standard.
Note 4. The device is not guaranteed to function outside its operating conditions.
Note 5. The dropout voltage is defined as VIN - VOUT, which is measured when VOUT is 98%*VOUT.
Note 6. The output voltage Auto discharge function is optional.
