GS7129
General Description
The GS7129 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 300mA output current, and
supports preset 1.1V, 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 output voltage
versions.
Based on its low quiescent current consumption
and its less than 1uA shutdown mode, the
GS7129 is ideal for battery- powered applications.
The high power supply rejection ratio of the
GS7129 holds well for low input voltages typically
encountered in battery- operated systems. The
regulator is stable with small ceramic capacitive
loads (1µF typical).
