GS7108
General Description
The GS7108 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 150mA output current, and
supports preset 1.2V, 1.3V, 1.5V, 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, 3.8V, 4.0V, 4.2V, 4.5V,
4.75V, 4.8V, 5.0V output voltage versions.
Based on its low quiescent current consumption
and its less than 1uA shutdown mode, the
GS7108 is ideal for battery- powered applications.
The high power supply rejection ratio of the
GS7108 holds well for low input voltages typically
encountered in battery- operated systems. The
regulator is stable with small ceramic capacitive
loads (0.47µF typical).
