GS7108ST-3P3-R

Low Noise 150mA LDO Regulator GS7108 General Description Features  Low Supply Current ~ 36uA (Typ.) The GS7108 is a CMOS linear regulator. It is  Low Shutdown Current ~0.1uA (Typ.) featuring ultra-high power supply rejection ratio,  Output Current ~150mA low output voltage noise, low dropout voltage, low  High Power Supply Rejection Ratio quiescent current and fast transient response. It ~78db@1KHz guarantees delivery of 150mA output current, and  1.7~6.5V Operation supports preset 1.2V, 1.3V, 1.5V, 1.8V, 1.85V,  ±1.0% Initial Voltage Accuracy 1.9V, 2.0V, 2.3V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V,  Low Temperature Drift Coefficient ~50ppm 2.9V, 3.0V, 3.1V, 3.3V, 3.8V, 4.0V, 4.2V, 4.5V,  Line Regulation ~0.02%/V(Typ.) 4.75V, 4.8V, 5.0V output voltage versions.  Low ESR Capacitor ~0.47uF ceramic  capacitor Based on its low quiescent current consumption uDFN4-1x1、xDFN4-1x1、SOT-23-5、SC-82、 and its less than 1uA shutdown mode, the MSOT-23 package GS7108 is ideal for battery- powered applications. The high power supply rejection ratio of the  Green Product (RoHS, Lead-Free, GS7108 holds well for low input voltages typically Halogen-Free Compliant) encountered in battery- operated systems. The regulator is stable with small ceramic capacitive Applications  Portable communication equipment  Notebook Computer  Battery Powered Systems loads (0.47µF typical).
