The circuit accepts at the input a \u201cnoisy\u201d dual supply voltage up to \u00b115 V and gives at the output precise, low noise, and stable voltages that can be set between \u00b13.75 V and \u00b112.5 V in eight 1.25 V steps. Particular care in circuit design, component selection, and proper filtering results in a noise spectral density of 50nV\/Hz at 1 Hz and 20nV\/Hz white when the output is set to \u00b15 V. This corresponds to 125 nV RMS (0.8 \u03bcV peak to peak) between 0.1 Hz and 10 Hz, and 240 nV RMS (1.6 \u03bcV peak to peak) between 0.1 Hz and 100 Hz. The power supply rejection ratio (PSRR) of the circuit is 100 dB at low frequency, and larger than 40 dB up to high frequency, thanks to a proper compensation design. Calibration allows to reach a precision in the absolute value of the output voltage of \u00b170 ppm, or \u00b1350 \u03bcV at \u00b15 V, and to reduce thermal drifts below \u00b11 ppm\/\u2218C in the expected operating range. The maximum peak output current is about 6 A from each output. An original foldback protection scheme was developed that dynamically limits the maximum output current to keep the temperature of the output transistors within their safe operating range. An add-on card based on an ARM Cortex-M3 microcontroller is devoted to the monitoring and control of all circuit functionalities and provides remote communication via CAN bus.<\/jats:p>","DOI":"10.1063\/1.4948390","type":"journal-article","created":{"date-parts":[[2016,5,9]],"date-time":"2016-05-09T17:00:21Z","timestamp":1462813221000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":18,"title":["A low noise and high precision linear power supply with thermal foldback protection"],"prefix":"10.1063","volume":"87","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7820-2732","authenticated-orcid":false,"given":"P.","family":"Carniti","sequence":"first","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare Sezione di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"},{"name":"Universit\u00e0 di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9611-1626","authenticated-orcid":false,"given":"L.","family":"Cassina","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare Sezione di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"},{"name":"Universit\u00e0 di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2501-9608","authenticated-orcid":false,"given":"C.","family":"Gotti","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare Sezione di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"},{"name":"Universit\u00e0 di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Maino","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare Sezione di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"},{"name":"Universit\u00e0 di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3700-9757","authenticated-orcid":false,"given":"G.","family":"Pessina","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare Sezione di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"},{"name":"Universit\u00e0 di Milano Bicocca INFN, , Piazza della Scienza 3, I-20126 Milano, Italy and Dipartimento di Fisica, , Piazza della Scienza 3, I-20126 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2016,5,9]]},"reference":[{"issue":"3","key":"2023080405495041100_c1","doi-asserted-by":"publisher","first-page":"775","DOI":"10.1016\/j.nima.2003.07.067","article-title":"CUORE: A cryogenic underground observatory for rare events","volume":"518","year":"2004","journal-title":"Nucl.
