The 50 denotes 5.0V fixed output, Q indicates AEC-Q100 automotive qualification, DGN denotes HVSSOP-8 PowerPAD package, R denotes tape and reel (2500 pcs\/reel), and Q1 confirms the automotive -Q1 product designation. The device operates from a wide 4V to 40V input range with 45V transient tolerance, making it suitable for direct off-battery (12V\/24V automotive battery) connection. The ultra-low 12uA typical quiescent current is critical for always-on standby systems where battery drain must be minimized during vehicle sleep modes. The 300mV typical dropout voltage at 150mA allows operation down to 5.3V input while maintaining 5V regulation. A programmable power-good (PG) reset delay is set by an external capacitor on the CT pin, providing a controlled startup sequence for the supervised MCU. The low-voltage tracking feature allows the output to follow the input during cold-crank transients, eliminating the need for a boost converter. Short-circuit protection and thermal shutdown ensure robust operation in harsh automotive environments.","working_principle":"The TPS7A6650QDGNRQ1 operates through four subsystems: (1) Pass Element Regulation: A P-channel MOSFET pass element regulates the output to 5.0V by controlling the gate voltage in response to the feedback error amplifier output. The 300mV dropout at 150mA means the MOSFET requires only 300mV VDS headroom to maintain regulation. (2) Low Iq Architecture: The 12uA quiescent current is achieved by biasing the error amplifier and bandgap reference at minimal current levels. During shutdown (EN = Low), all internal circuits are disabled and the pass element is turned off, reducing supply current to only 2uA. (3) Power-Good Reset: The PG open-drain output is pulled low when VOUT drops below 90% of the nominal 5.0V. When VOUT exceeds 90%, an internal current source charges the external CT capacitor. The PG output releases high when the CT voltage exceeds an internal threshold. With 100nF on CT, the reset delay is approximately 100ms. Without CT, the default delay is 290us. (4) Low-Voltage Tracking: When VIN drops below the minimum input for regulation (dropout region), the output tracks the input minus the pass element voltage drop. This allows the system to gracefully ride through cold-crank transients without generating a reset, as long as the MCU can operate at reduced voltage.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>EN<\/td><td>Input<\/td><td>Enable (active high, connect to VIN for self-bias)<\/td><\/tr><tr><td>2<\/td><td>VIN<\/td><td>Power<\/td><td>Input voltage (4-40V, up to 45V transient)<\/td><\/tr><tr><td>3<\/td><td>VOUT<\/td><td>Power<\/td><td>Regulated 5.0V output<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>NC\/FB<\/td><td>-<\/td><td>No connect (fixed output version)<\/td><\/tr><tr><td>6<\/td><td>CT<\/td><td>I\/O<\/td><td>Reset delay capacitor (open = 290us default)<\/td><\/tr><tr><td>7<\/td><td>PG<\/td><td>Output<\/td><td>Power-good reset (open-drain, active low)<\/td><\/tr><tr><td>8<\/td><td>GND<\/td><td>Power<\/td><td>Ground (PowerPAD)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Always-on 5V standby MCU supply from 12V car battery with 12uA Iq, PG reset, and cold-crank tracking<\/li><li>Body control module 5V rail with 40V overvoltage tolerance, programmable 100ms PG delay, and short-circuit protection<\/li><li>Remote keyless entry receiver 5V supply with 2uA shutdown current during vehicle sleep mode<\/li><li>Gateway module with EN controlled by ignition switch, 45V transient protection, and AEC-Q100 Grade 1 qualification<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Vout<\/th><th>Iq<\/th><th>Notes<\/th><\/tr><tr><td>TPS7A6633QDGNRQ1<\/td><td>TI<\/td><td>3.3V<\/td><td>12uA<\/td><td>3.3V fixed output version<\/td><\/tr><tr><td>TPS7A6601QDGNRQ1<\/td><td>TI<\/td><td>Adj<\/td><td>12uA<\/td><td>Adjustable output version<\/td><\/tr><tr><td>TLE4274SV<\/td><td>Infineon<\/td><td>5V<\/td><td>~30uA<\/td><td>Automotive LDO, TO-263<\/td><\/tr><tr><td>NCV4264-2CST5T3G<\/td><td>onsemi<\/td><td>5V<\/td><td>~28uA<\/td><td>Auto LDO with watchdog<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5461","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=5461"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5461\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=5461"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=5461"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=5461"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=5461"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
