GS7119
Features
General Description
Low Supply Current~55uA (Typ.)
The GS7119 is a CMOS linear regulator. It is
Low Shutdown Current ~0.1uA (Typ.)
featuring ultra-high power supply rejection ratio,
Output Current ~300mA
low output voltage noise, low dropout voltage, low
High Power Supply Rejection Ratio
quiescent current and fast transient response. It
~75dB@1KHz
guarantees delivery of 300mA output current, and
1.7~5.5V Operation
supports preset 1.2V, 1.3V, 1.5V, 1.7V, 1.8V,
±1.5% Initial Voltage Accuracy
1.85V, 1.9V, 2.0V, 2.3V, 2.5V, 2.6V, 2.7V, 2.8V,
Low Temperature Drift Coefficient ~50ppm

versions.
Low ESR Capacitor ~1.0uF ceramic capacitor
Based on its low quiescent current consumption
WDFN4-1.2x1.6、TDFN6-1.8x2、SOT-23-5、
and its less than 1uA shutdown mode, the
SOT-89-3、MSOT-23 and SOT-353 package
GS7119 is ideal for battery- powered applications.
Green Product (RoHS, Lead-Free,
