The output voltage is adjustable from 1.25V to 16V using an external resistor divider. On-chip trimming achieves 1% initial output voltage accuracy. The device provides comprehensive fault protection including overcurrent, reverse battery, and positive\/negative voltage transient immunity. With 600mV dropout voltage at full 3A load and zero-current shutdown mode, it is ideal for battery-powered and high-efficiency applications. The TO-263-5 package enables excellent thermal performance with surface mount assembly.","working_principle":"The XRP29302 uses a PNP pass transistor in a low-dropout configuration. The internal 1.25V bandgap reference is trimmed on-chip for 1% accuracy. An error amplifier compares the feedback voltage (from the ADJ pin) with the internal reference and drives the PNP pass element to maintain the desired output voltage. The output voltage is set by two external resistors: VOUT = 1.25V x (1 + R1\/R2) + IADJ x R2. The ENABLE pin provides a zero-current shutdown mode. Overcurrent protection limits the pass transistor current during fault conditions, while thermal shutdown protects against excessive junction temperature.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>OUT<\/td><td>Regulated output voltage<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>IN<\/td><td>Unregulated input voltage (2.25V-16V)<\/td><\/tr><tr><td>4<\/td><td>ADJ<\/td><td>Adjustment feedback pin<\/td><\/tr><tr><td>5<\/td><td>EN<\/td><td>Enable\/Shutdown (active high)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Adjustable power supplies for FPGA and processor core voltages<\/li><li>Post-regulation after switching converters for low-noise rails<\/li><li>Battery charger regulation circuits<\/li><li>Audio and video graphics card local power regulation<\/li><li>Constant current source applications using the ADJ pin<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Notes<\/th><\/tr><tr><td>SPX29302<\/td><td>Original Sipex design, drop-in compatible<\/td><\/tr><tr><td>LT1085CT-ADJ<\/td><td>Analog Devices 3A LDO alternative<\/td><\/tr><tr><td>LM1085IT-ADJ<\/td><td>Texas Instruments 3A LDO alternative<\/td><\/tr><tr><td>LD1085V<\/td><td>STMicroelectronics 3A LDO alternative<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3640","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=3640"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3640\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=3640"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=3640"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=3640"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=3640"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
