Features: Instead of using ICs (integrated circuits), we have a fully discrete topology, single pass, series regulator design. This allows complete design control over all operating points and parameters for superior performance. Low noise, high PSRR A constant-current source feeds a zener diode as a stable voltage reference. A low-pass filter (with a corner requency of 1.6Hz) prevents zener noise from being introduced into the error amplifier. This is an effective yet lower-cost alternative to expensive voltage reference ICs. The low-pass filter also provides a soft-start characteristic. This is much better than the noise of an IC regulator based PSU tested under identical conditions. The error amplifier is a discrete implementation of an opamp with a high open-loop gain of 102.5dB. The voltage supply to the error amplifier is isolated with capacitance multipliers to boost its PSRR (power supply rejection ratio). This greatly improves the performance of PSU line regulation. A long tail pair differential amplifier with current mirror and constant current source forms the first stage of the error amplifier. The second stage is the voltage amplification (EVA) stage, also with constant current source load. The 3rd stage consists of the power MOSFET output devices configured as a source follower. High Current MOSFET Pass Transistors Two high-current and highly reliable parallel MOSFETs (rated 17A each) serve as the "passage" transistor. High chain rating provides very high safety space against overcurrent damage. The use of parallel MOSFETs divides heat dissipation, simplifying thermal management. Onboard heat sinks can be used which would allow this PSU to provide up to 1A continuous (with much higher peak value currents). More sustained chains are possible using larger and offboard heat sinks. The negative temperature coefficient of MOSFETs prevents harmful thermal leakage conditions that may affect conventional BJT devices. No chain limitation.
