ES9311Q Datasheet | ESS Technology

features not available in modity regulators: the two outputs require no decoupling capacitors, remote load sensing ensures output voltage accuracy right at the load, there are two output enable inputs, the outputs have a soft-start function, plus power-good, over-temperature warning, and over-temperature shutdown outputs. The ES9311Q Dual, Ultra-Low Noise Linear Regulator is available in a 30-pin, 3mm x 5mm QFN package. FEATURE o Dual outputs with 300m A total load o < 1µVrms output noise (100Hz to 100k Hz) o Operating from +3.5V to +5.5V o Excellent line and load regulation o Remote sensing for each output o Five enable inputs and four status outputs o Over-current & over-temperature protection o 3.5m A total quiescent current o 30-QFN package, 3mm x 5mm BENEFIT o Dual regulator minimizes board space requirements o Low noise is required to achieve high converter DNR o Wide supply range operation o Maintains accurate Vout with line/load variations o Enables excellent load regulation, typically 16m V/A o Provides design flexibility and host munications o Protects regulator against system fault conditions o Suitable for USB and battery powered designs o Minimizes PCB footprint ESS TECHNOLOGY, INC. 109 Bonaventura Dr. San Jose, CA 95134, USA.
