With 36V maximum input, 500mA output current, and only 200mV dropout, it provides 72dB PSRR and 6.5\u03bcV RMS output noise\u2014ideal for noise-sensitive automotive ADAS, infotainment, and sensor power rails. The adjustable output starts from 0.8V, and the enable pin supports power sequencing. Packaged in a compact SOT-89-5 with robust current limit and thermal shutdown protection.","working_principle":"The MPQ8901DD-AEC1 operates as a series-pass linear regulator. A precision bandgap reference provides the target voltage, and an error amplifier drives the pass transistor to maintain the output at the programmed level. The ultra-low noise performance is achieved through optimized internal biasing and a noise-reduction capacitor on the reference pin. The high PSRR results from the high open-loop gain of the error amplifier and the low output impedance of the pass element. Current limiting is implemented by sensing the pass transistor current and limiting the gate drive when the threshold is exceeded. Thermal shutdown disables the pass element when the junction temperature exceeds the safe limit.","pin_description":"<table><tr><th>Pin<\/th><th>Mnemonic<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>EN<\/td><td>Enable input (active high)<\/td><\/tr><tr><td>2<\/td><td>IN<\/td><td>Input supply voltage (2.5-36V)<\/td><\/tr><tr><td>3<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>4<\/td><td>OUT<\/td><td>Regulated output voltage<\/td><\/tr><tr><td>5<\/td><td>ADJ<\/td><td>Feedback \/ adjustment pin<\/td><\/tr><\/table>","application_scenarios":"<ul><li>ADAS radar module power supply requiring ultra-low noise and high PSRR<\/li>\n<li>Automotive camera sensor clean power rail with 36V input tolerance<\/li>\n<li>RF transceiver and PLL power post-regulation after buck converter<\/li>\n<li>Infotainment DAC and audio codec power with 6.5\u03bcVrms noise<\/li>\n<li>Precision analog front-end power supply in automotive ECU<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>TPS7A1650<\/td><td>TI<\/td><td>40V, 150mA ultra-low-noise LDO<\/td><\/tr><tr><td>LT3042<\/td><td>ADI<\/td><td>20V, 200mA ultra-low-noise LDO<\/td><\/tr><tr><td>NCP591<\/td><td>onsemi<\/td><td>45V, 150mA automotive LDO<\/td><\/tr><tr><td>MPQ8902DD-AEC1<\/td><td>MPS<\/td><td>Higher current version<\/td><\/tr><tr><td>MAX25210<\/td><td>ADI<\/td><td>36V, 200mA AEC-Q100 LDO<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9149","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=9149"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9149\/revisions"}],"predecessor-version":[{"id":9494,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9149\/revisions\/9494"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=9149"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=9149"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=9149"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=9149"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
