Koheron QPS100P is a linear power supply that can drive up to 2 A. Its low noise (1.1 nV/√Hz at 1 kHz) helps getting the full performance of critical analog components (amplifiers, data converters, oscillators, phase lock loops, ...). Thanks to its high ripple rejection and low drop voltage, QPS100P is ideal for switched mode supplies post-regulation.
