Designed for battery-powered and noise-sensitive applications, it features ultra-low dropout voltage (10mV at light loads, 350mV typical at full load) and ultra-low output noise when used with an external bypass capacitor. The wide 2.5V-16V input range supports diverse supply topologies. Reverse battery protection, current limiting, and thermal shutdown provide robust fault protection. The SOT-223-3 package offers excellent thermal dissipation in a compact footprint.","working_principle":"The MIC5209 uses a P-channel MOSFET pass element driven by an error amplifier that compares a fraction of the output voltage with an internal reference. The 1% bandgap reference ensures tight output accuracy. When a bypass capacitor is connected to the BYP pin, it filters reference noise to achieve ultra-low output noise. The EN pin enables or shuts down the regulator; in shutdown, quiescent current drops to near-zero. Reverse battery protection prevents damage when input polarity is reversed. Current limiting and thermal shutdown protect against overload conditions.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>IN<\/td><td>Input Supply (2.5-16V)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground (Tab)<\/td><\/tr><tr><td>3<\/td><td>OUT<\/td><td>Regulated Output (3.3V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Battery-powered portable device 3.3V rail<\/li><li>RF transceiver and analog front-end low-noise supply<\/li><li>USB peripheral 3.3V power regulation<\/li><li>Post-regulation after DC-DC converter for noise filtering<\/li><li>Precision sensor and ADC reference supply<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Vout<\/th><th>Notes<\/th><\/tr><tr><td>Microchip<\/td><td>MIC5209-3.0YSTR<\/td><td>3.0V<\/td><td>Same family, 3.0V output<\/td><\/tr><tr><td>TI<\/td><td>TLV1117-33<\/td><td>3.3V<\/td><td>800mA LDO equivalent<\/td><\/tr><tr><td>Microchip<\/td><td>MCP1824T-3302E\/OT<\/td><td>3.3V<\/td><td>300mA, SOT-23-5<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10396","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=10396"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10396\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=10396"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=10396"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=10396"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=10396"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
